- The Pureboost Trainer is a versatile workout shoe from Adidas created with cross-training and running in mind. The model is fittingly named after the acclaimed Boost technology found in its midsole unit. Made up of tiny thermoplastic-polyurethane (TPU) pellets which are fused together, Boost creates a responsive platform for jumping, running, and other high-impact activities.
- The trainer’s platform is made with a noticeably greater footprint compared to most workout footwear. It is guarded by a rubber outsole which extends up all around the shoe for ultimate durability.
- A breathable knit material is employed in the upper unit to promote freedom of movement. At the same time, an elastic strap around the ankle offers support and a secure foothold.
A durable rubber material protects the bottom portion of the Pureboost Trainer. It extends up all around the shoe, entirely covering the midsole and partially enveloping the upper. That way the outsole not only shields the trainer but also contributes to the overall stability of the foot.
The rubber has a jagged texture with both horizontal and vertical treads. It is meant to provide grip on various types of training surfaces, including smooth and wet ones.
The hallmark feature of the trainer is its full-length Boost midsole. This unit is comprised of small TPU balls which have a lightweight and extremely springy nature. When molded together, these pellets create a platform that compresses upon impact yet quickly restores its original shape when pressure is removed. This responsive cushioning protects the wearer’s foot during training and running while also giving a little energy boost, as its name implies. Another highly-rated cross-trainer from Adidas that employs the Boost midsole is the Crazy Train Elite.
Both the midsole and the outsole of this model are designed to be wide in the heel and the forefoot. There is also a protruding outrigger on the lateral side of the forefoot. Such construction ensures a stable stance for the wearer to eliminate the chance of foot wobbling and sliding off the sole’s edge.
The Adidas Pureboost Trainer utilizes a breathable knit material in its upper unit. It is created to conform to the wearer’s foot offering a snug yet unrestrictive fit. It allows the foot to bend naturally while also keeping it fresh.
There is a supportive strap placed around the shoe’s collar. It locks the fit in the ankle area to keep the shoe securely on. The elastic nature of the strap allows it to stretch when the shoe is put on and removed. Due to the low-cut design of the footwear, the strap does not hinder the freedom of ankle movement.
A lacing system is added to regulate the tightness of the fit. It is a little bit tilted towards the inner edge of the upper to provide a more efficient lateral support.
