Altra Duo Review Facts

Altra Shoes are perfect for any individual who would like to have a shoe that will consistently provide them with the control that they’d need on their terrain of choice. The Altra Duo is a shoe that was designed to be as responsive as possible and provide wearers with adequate grip and comfort when they’re out tackling a terrain such as a road. The design of their shoes and the features present to ensure that wearers have everything that they need in order to make the most of their exercise of choice, typically running.

Editor's Pros & Cons
Pros
  • Well-cushioned
  • Lightweight
  • Breathable Design
Cons
  • Chafing may occur
Outsole

Outsole

The outsoles of many of Altra’s shoes are designed in rather peculiar fashions. They either have designs that are meant to fully conform to the shape of the wearer’s foot or have designs that don’t conform at all. In this case, the design is one that is meant to be a mixture of both realities. The outsole of the Duo is blocked off into sections of tread material. They allow wearers to have adequate room to flex while in the shoe as well as remove a bit of the weight from the shoe’s design. On that same note, the design makes use of blown rubber in order to provide wearers with adequate grip while running.
Midsole

Midsole

The midsole of the Duo may seem bulky at first glance, but it’s because the shoe is meant to provide maximum comfort to the foot. The midsole has a design that makes use of Injection molded foam in order to provide wearers with a cushioned and responsive feel during their run. The use of this foam material resulted in a drop that is a bit higher than that which is average(will be discussed throughout the article). The weird thing about the cushioning in the shoe is that, although it provides adequate comfort to the wearer’s foot, it doesn’t result in a feel that is outstandingly pillow-like.
Upper

Upper

The upper of the Duo is designed from a relatively thin mesh material. This material enables the wearer to make the most of their transitions and results in smooth-(er) overall rides when the shoe is in use. There are a few reinforcements in place around the toe area and heel of the shoe which gives the shoe a bit of structure and prevents any premature damage that may come to the shoe’s design. The heel cup of the shoe is designed from a rubber material (it gives the design a bit of variation) that contrasts the responsive nature of the mesh in the shoe’s design. The Duo also features a low-top design; this makes entry and removal of the shoe a relatively simple task as well.
Weight

Weight

The wonderful thing about the peculiarities that are in this shoe’s design is that they result in a shoe that is rather lightweight. Before anything else about the shoe’s design is mentioned, the entirety of the shoe weighs roughly 8.4 ounces for a men’s size 10; this is incredible considering the bulky design of the shoe. One thing that must have attention paid to it is that the entire design of the shoe is put together with the idea in mind that wearers would like to have an overall lightweight experience while they are out running. For this reason, Altra placed the spaces in the shoe’s design and gave it a relatively minimal upper design.
Breathability

Breathability

If one is looking for a shoe which will provide them with adequate airflow and circulation, it wouldn’t be a bad idea to give this shoe a look-over. The upper of the Duo is designed from a thin cut of mesh. This material is meant to provide wearers with the airflow that they’d need in order to fully experience the movements that they make while in the shoe. On that same token, the use of mesh in the design of the shoe also allows it to provide a moisture wicking effect to the shoe; it becomes very difficult for sweat to build up in the shoe’s upper.
Comfort

Comfort

The breathability that the shoes upper provides instant comfort to any individual who likes to run in warmer areas. Another aspect of the shoe’s design that is meant to provide wearers with adequate comfort is the midsole area of the shoe. The midsole and the blown foam material incorporated is relatively thick and meant to provide wearers with a cushioned yet firm feel during their run. It doesn’t sag and fail to provide the wearer with even a semblance of stability while in use, which is an incredibly good thing. The one thing that wearers should pay attention to is the heel area of the shoe; it tends to chafe the ankle if worn for too long or without socks of adequate length.
Style

Style

Well, these are definitely running shoes; one can tell that from simply looking at the design of the shoe. The Duo has a slim cut and various other features such as the breathable materials which ensure that wearers receive what they’d need in terms of functionality from the shoe. Let’s not forget to mention that the shoe is what many individuals would like to call quite stylish. It comes in a few color schemes and each of them make it relatively simple to match the shoe with the outfit of your choice.
Durability

Durability

Altra shoes are praised for the durability that comes incorporated into their designs. Again, the Duo hasn’t strayed too far from that which is native to this brand. The outsole of the Duo is made from blown rubber and despite what many say is native to this material, still manages to have quite a bit of longevity. It wears evenly and due to the fact that it is so thick shouldn’t lose it’s gripping abilities quickly. The midsole is the exact same way except with this it’s the cushioning that manages to last for a long time. The midsole is so thick that it becomes a difficult task for it to compress all of the ways and reduce the comfort that the wearer receives from the shoe over time.
Protection

Protection

One area that the shoe’s upper may be lacking in is that of protection. The design elements of the upper such as the mesh won’t do much to keep the wearer’s feet dry in wet climates. This isn’t the worst thing about a shoe but it should be taken note of. The mesh in the upper of the shoe is relatively thin which works wonders for breathability but doesn’t give the shoe what it needs in order to keep liquids out of the upper. The midsole on the other hand is so thick that it becomes quite difficult for it not to protect the foot from incoming elements.
Responsiveness

Responsiveness

One thing that is somewhat surprising about the design of the Duo is that it still manages to be responsive despite the bulky midsole region. The midsole is thick but the foam compresses just enough to give the wearer the comfort that they’d need to gain from the shoe. This means that the material will bend under the weight of the wearer’s feet just enough to provide them with the cushioning that they’d need in order to feel comfortable in the shoe. The upper is very much the same way except that with the upper, it doesn’t take much for its move to the needs of the wearer’s foot; as mentioned earlier, it’s relatively thin.
Support

Support

The injection molded foam in the midsole of the shoe will consistently provide wearers with what they’d need in order to feel comfortable in their Duo. To feel comfortable, it is important that a shoe provides at least a semblance of support to the wearer’s foot. The cushioning provided by the foam conforms to the shape of the foot and is meant to provide wearers with adequate support during their run. The material works best for those runners who have a neutral gait.
Terrain

Terrain

Another great thing about the Duo is that it works well on several terrain types. The outsole is rather durable due to the fact that it’s designed from blown rubber and manages to provide wearers with what they’d need on both roads and in actual gyms. On that same note, I want you to keep in mind that the shoe can also be used on off-road activities such as for cross-country; it just shouldn’t be used for trail running since that isn’t what it’s meant for.
Price

Price

When the price and the longevity of the Duo are weighed side-by-side, one can see that the shoe has a decent level of value. The Duo sells for a relatively low price compared to other shoes of its caliber. The value of the Duo comes from both its durability and it’s traction gaining capabilities. Considering the price of the shoe and the time that was probably placed into its design, it makes sense to purchase this model.
Traction

Traction

This was touched on earlier in this review but, was never fully elaborated. The Altra Duo is meant to and will provide wearers with adequate functionality in the area that they decide is best to run in. For starters, even though blown rubber isn’t considered the most abrasive material, it will still stick to a surface if distributed properly. In addition to this distribution of the rubber, the fact that the shoe outsole is broken off into sections allows the shoe to provide the wearer with intelligent use of the material. It becomes much easier for the outsole to stick to various surfaces due to the flex incorporated into the design.
Flexibility

Flexibility

Again, this was touched upon but not in great detail. The outsole of the Altra Duo is broken off into a section which helps the shoe provide both flexibility and increases the effectiveness of the grip. The outsole’s flexing ability works in tandem with that of the upper; the upper manages to move easily and improve the transitions that are experienced while in the shoe. Something that may surprise you is that the midsole also manages to provide the wearer with a bit of flexibility as well. The cushioning manages to bend easily but still gives the wearer what they’d need in terms of firmness; this is something that not many see in a shoe of any design.
Stability

Stability

Most of the stability of this shoe comes from the design of the sole unit. The Duo’s sole unit is incredibly thick, it’s almost impossible for it to not give the wearer a semblance of security and stability when worn. The material still manages to compress and conform under the wearer’s weight, it just doesn’t do so as much as one would expect it to. To combat the thin nature of mesh in the upper, the shoe also makes use of overlays which allow it to provide the wearer with a bit of structure in the design. Believe it or not, this structure is what allows this shoe to perform to such a high level on various terrains.
Drop

Drop

As is customary of Altra shoes, the design of the Duo features zero-drop. This means that there is literally no rise from the heel of the shoe to the toe area; it’s a solid platform. Despite the thickness of the material, it still allows the shoe to provide a natural feeling ride to the wearer. As mentioned in an earlier section, the shoe has relatively smooth transitions, and this is helped by the lack of drop.

• Sectioned outsole
Verdict

Verdict

This would be a wonderful choice for any individual who would like to have a shoe with both a solid yet relatively comfortable design. The cushioning in the midsole is what gives this shoe the early recognition that it has. For those who’re interested, it’s imperative to keep in mind that this shoe is also low-priced. A shoe with the comfort that this one has, as well as it’s low-price is one that shouldn’t be passed up.
