Available both in leather and vegan options, as well as a variety of colors, it will easily become your go-to this summer.Read more
The thing about Birkenstocks is that their footbed is made with anatomically shaped latex-cork that breaks in to match your foot perfectly, while supporting your arch (with quite a bit of height, so it’s appropriate even for those with high arches), a deep stabilizing heel cup, and a raised toe bar that makes walking much easier. This is a pair of footwear that will prevent you from overpronating, ensuring proper alignment, eliminating joint and back pain.

Criteria Used for Evaluation
The most important feature you want to be looking in any pair of shoes that you want to wear for flat feet is arch support. With sandals, this becomes more difficult to find as they are mostly made flat, lightweight and with minimal cushioning, support, and shock absorbing qualities. An added disadvantage of sandals is that they will often offer insufficient support on the top of the foot, meaning that unnecessary stress is put on certain parts of your feet.
Luckily, many manufacturers recognize the need for comfortable and supportive footwear for people with flat feet (especially since almost one-third of the world’s population suffers from this condition). A perfect pair of sandals for flat feet will have a contoured, anatomical footbed with arch support that will raise your arches and allow for correct foot positioning. This will help take pressure off of the rest of your feet, such as the heel and tendons in your feet, and may be an important factor in preventing arthritis, back pain or strains.
All of the models listed above have been chosen because they provide wearers with adequate support. While some people require a more customized footbed, most people will do all right with an anatomical footbed.
Some of the things you should check out before making a purchase are the following:
If you have flat feet, chances are you tend to overpronate, putting too much stress on the inner part of your feet. If you are unsure whether you do this, you can check by looking at a pair of well-worn shoes. Can you see any difference in the wear of the outsole? This will show up on the heel, as the inner parts will be more worn than the outer parts. Overpronation is a habit that is common among people with flat feet or fallen arches, seeing that the underfoot muscles are not strong enough or cannot stay up in their natural position.
Although the most common consequence of overpronation is hip and knee pain, as well as discomfort in the heels, some people who overpronate may also develop conditions such as hammer toes, corns or calluses, bunions or even heel spurs.
That’s why a good pair of shoes will prevent you from putting your weight on the inner part of your feet and will promote an even distribution throughout the whole foot. Luckily, this problem can be easily solved by choosing footwear that is supportive in the arch area, as this will return your feet to the correct alignment.
Sandals such as those made by Birkenstock and Vionic will do especially well as they provide the necessary firm support that will stop you from putting too much of your weight on your arches while standing and walking.
We have already covered how important it is for you to have correct alignment when standing and walking. You may find that although you have flat feet, your feet do not experience any pain, but your knees, hips or back do. If you tend to experience any pain in these parts of your body after periods of standing or walking, you need to check whether your weight is evenly distributed to your whole body.
This can be done in the same way you check for overpronation – just look at the soles of your shoes, and check whether any part is overly worn. The goal is to have your shoes be evenly worn through the whole sole, and symmetrically on both sides. If your feet are positioned correctly, your whole body will have the opportunity to adapt, which means that your ankles can rest at a natural angle, and your knees and hips will come back into alignment. Through doing this, you will help take off the stress of just a part of these joints, allowing them to work in their natural position.
Another result is that the muscular structure around these joints will also get the chance to return to a natural way of working, preventing strain and thus lowering the chance of you feeling pain when going about your everyday life.
People with flat feet will tend to put too much stress on the heel of their foot when walking, resulting in this body part taking too much of the shock on impact with the ground. Too much stress on the heel can result not just in pain, but also in developing conditions such as heel spurs which are much more difficult to treat and manage than flat feet.
Perfectly, your shoes will help absorb some of the shocks your body experiences while walking. Sandals with soles made out of rubber and EVA foam materials are an especially good choice, as they will usually have been made with plenty of walking in mind.
Another important feature you want to look for in your footwear is cushioning which will make you feel more comfortable throughout the day. Some styles on this list have soft microfiber or suede linings, while others have cushions in the heel and forefoot. It is best to find a pair that will feel best for you. More often than not, you will find that a properly fitted pair of shoes with the right amount of support will not just prevent symptoms, but will also feel incredibly good to stand and walk in.
The final universal criterion that you need to look for in any pair of shoes if you have flat feet is width. People with flat arches will tend to feel more comfortable in wider shoes as this allows the foot to flatten on its whole surface.
However, in order to really prevent the symptoms of flat feet, you first need to get the right arch support and then get a pair of shoes that are properly fitted in width.
Sandals can be a very comfortable option when it comes to width as most are adjustable and will allow you to customize the fit of the upper so that you do not feel any unnecessary pressure on your metatarsal area while still retaining a secure fit in the heel. Some makers will make shoes in different widths, and these will have a slightly wider outsole which will ensure that your whole foot is properly protected and supported throughout the day. If, however, you feel that a pair of shoes is too narrow, you will probably want to skip wearing them, as they might contribute to developing other ailments such as bunions, calluses, and corns, or even blisters which can be very difficult to manage, especially in hot and humid climates.
Another thing worth mentioning is that you should never wear a pair of footwear that isn't your size (this goes for both length and width). If your shoes are too long for you, you'll find that the arch support isn't where it's supposed to be, preventing you from benefiting from the supportive features. Fit really is crucial when it comes to healthy feet, so don't sacrifice it just because you think a pair of shoes looks cute.
Supposing that you are purchasing a pair of sandals for summer use, it is very important to consider the materials that have been used to make the upper.
Generally, if you are going to be spending a lot of time in a hot environment, you will want your footwear to be made out of lightweight, breathable materials that won’t cause irritation or profuse sweating when worn for a longer period of time. Most sandals on this list are made out of synthetic uppers which will help wick moisture away from your feet, or from leather which is porous and breathable.
It is also good to have some slight stretch in the upper of your summer sandals, as this will ensure a better fit, but will also allow your feet to swell slightly, which will inevitably happen from the heat and lots of walking.
The inner lining also needs to use high-quality materials as you want the part of the shoe that touches your feet to be soft, breathable and to dry quickly enough. Antimicrobial and anti-odor treatments are a great addition as these will prevent the formation of odors or bacterial and fungal infections which tend to happen in hot and humid environments.
Expert Interviews & Opinions
Many times, when we think of supportive footwear, an image of something not quite so stylish may come to mind. But with brands evolving to meet the needs of consumers, they've melded together fashion and function. Many stylish options are available, with intricate stitching designs, color options, and strappy style to keep your look on point.
Pairing sandals is quite easy for a sleek summer look. Go for something with more design elements, like stitching or colors, to boost your outfit to something more polished. Sporty sandals can be worn with just about any attire, and make it easy should you find yourself off the beaten path for a bit of adventure.
Other Factors to Consider
Shopping for sandals with a generous amount of arch support is often frustrating. Because this type of footwear (almost) never includes a removable footbed, you can’t just do what you’d do with regular shoes - remove the insoles and replace them with custom orthotics. Instead, you need to look for models that already have an appropriate level of arch support, plus that have the necessary features for the type of wear you’re interested in.
Overall, finding supportive sandals will be much easier for those who are ready to wear models made for hiking. In addition to anatomical footbeds, these will also often feature protective uppers, moisture wicking linings, as well as tractioned outsoles that will work well on all types of surfaces. They will also often have multiple adjustment points that allow for wearers to find the best fit.
Other options include anatomical footwear, but this type will usually be more casual than elegant. Birkenstocks are a great example of this - and while they can be combined with certain outfits, they unlikely to be appropriate for formal occasions.
For beach and pool wear, you will probably do great with simpler models. The OOFOS Ooriginal is great, but you can also go with a simple pair of Crocs that ensure proper alignment, and are cushioning enough to be worn all day, without you having to worry about material deterioration due to moisture.
Everyone will probably use their summer sandals for different occasions, so you need to consider how you want your sandals to serve you. Do you plan on wearing them to the office, or do you prefer to wear them for long hikes in nature? Will you be taking them to the beach, or are you more of a city kind of person? It is important to choose the correct sandal, especially for activities that require special features. If you plan on going hiking, you will need a sturdier sandal that will provide better shock absorption and cushioning so that you can feel comfortable after several hours. If you plan on heading to the beach, your sandals will need to be water friendly – this not only means a rubber outsole, but also upper and lining materials that will dry more easily than leather or cork.
Some people may work as servers at restaurants, which will require a non-slip sole for safety reasons. Before making a purchase, make sure to check whether your favorite choice ticks all the boxes for the type of use you intend to get out of your footwear. And although the style is important, fit should always take first place when prioritizing.
Last but not least, when purchasing a pair of sandals, you want to get a pair that will fit your feet in the correct way, and that includes a secure fit of the upper. As sandals have much less material on the upper than regular shoes, it is crucial that they are safely on your feet to prevent putting too much stress on certain parts of your feet. This includes making sure that they are properly fitted at the heel and ankle.
The best choices will be fully adjustable shoes with secure buckles that won’t give in after a few uses. Our favorites for their level of adjustability are the ECCO Yucatan, Vionic Gerrit, and Chaco Zvolv X2 W, all of which will allow you to choose your own perfect fit in multiple points on the sandals.
Frequently Asked Questions
q: What are the symptoms of flat feet?
Some people who have flat feet will never experience any symptoms. Others, however, will feel pain in their arches, tendons, ankles, knees, hips or back. If you have flat feet and leave them without the support they need, you may find that you will start overpronating which can lead to even more consequences such as hammer toes, calluses, and corns, heel spurs or even arthritis.
q: How to prevent symptoms related to flat feet?
Luckily, the consequences of flat feet can be prevented very easily. Although your podiatrist may prescribe you with medication or exercise to manage pain and to strengthen your arches, you will easily avoid experiencing any symptoms at all if you opt for footwear that gives you the correct arch support and that will help you align your feet correctly so as to avoid putting too much stress on certain parts of your feet or other joints in your body.
q: Are flat sandals a good option of footwear if I have flat feet?
Generally, sandals will not be the best option for you if you have flat feet, as most models have a completely flat sole without cushioning and shock absorbing properties, and that doesn’t provide you with the anatomical support you need. In addition, the uppers of sandals can often be flimsy, adding unnecessary stress to your feet which will have to work overtime in order to keep your footwear on. All sandals on our list have been chosen because they possess the features that are necessary for anyone with flat feet, but even among these, you may find that some models work better for you than others.
q: How do I know whether my shoes offer enough arch support?
A good pair of shoes will hug your arches even when you are sitting. You will find that the raised part of the shoe gently lifts your feet and prevents you from sinking into the inner part of your feet. You can check this by looking at the soles of the shoes and seeing whether they are more worn on the inside than on the outside portion. In addition, with insufficient arch support in your shoes, you are likely to experience foot, knee, hip or back pain after a period of standing or walking.
q: What materials are good to look for in sandals for flat feet?
The best materials to look for are shock absorbing rubber or EVA foam, but some makers make excellent shoes out of other materials as well, such as Birkenstock sandals which have cork soles.
q: I’m not sure what size I need? Should I size up or down?
If you are unsure what size to get, you can always read the reviews on Amazon, which will tell you whether a particular shoe fits smaller or larger than expected. If you still don’t know, you can either visit a brick and mortar store to be fitted or order a pair of shoes in both sizes, then return the ones which don’t fit well. As with any type of footwear, it is crucial that your sandals fit well, as the arch support needs to be in the correct place for you to actually get its benefits.
