Good to know

  • The Adidas Pure Boost X Training Shoe is the training version of the same-name running shoe. It’s marketed as a premium, lightweight trainer for women and is designed to tackle a variety of training activities. It features Adidas’ proprietary boost™ technology to deliver an enhanced energy-return.
  • A combination of textile, mesh and synthetic materials in the upper creates a breathable and snug support for the foot. The gap between the midsole and the top supports the natural movement of the foot. The rubber outsole makes use of the pivot point for smooth rotational moves. 

The Adidas Pure Boost X Training Shoe was designed for women. It is available in women’s version only and runs true to size. It accommodates medium-sized feet as it is offered in a B – Medium width profile. Consumers are advised to try the shoe in person to get a secure and agreeable fit.

The Adidas Pure Boost X Training Shoe utilizes a rubber outsole. This compound is durable and flexible and provides optimum grip. It has a pivot point underneath the ball of the foot which allows for smooth and easy twists and turns. The material is also non-marking which means it does not leave scuff marks on floors.

The structure of the outsole resembles a rocker. This design provides the necessary flexibility for the natural bending of the foot and a smooth heel-to-toe-off motion.

The midsole of the Pure Boost X Training Shoe features the proprietary boost™ technology for cushioning and enhanced energy return. It is a full-length foam unit made from the compaction of small, elastic thermoplastic polyurethane (TPU) pellets and subjecting it to heat treatment. The result is a soft and springy foam material that ensures each step is charged with an endless supply of energy.

The upper of the Adidas Pure Boost X Training Shoe employs the combination of textile and mesh. The mesh fabric ensures that the foot chamber is well ventilated while the textile enhances its overall structure and durability.

The synthetic overlays form a cage-like structure in the midfoot area. They integrate with the lacing system and enhances the lateral support of the upper when the laces are tightened.

The gap between the upper and the midsole forms a floating arch. This curvature hugs the arch for support and promotes natural foot movement.
