Description
Men's running trainers. Neutral high-performance training model for runners looking for excellent cushioning, intended for medium-weight to heavy runners training 1 to 7 days per week. They are also good for recovery.
The upper is made of customised and lightweight textile that facilitates ventilation thanks to the VTS system, and welded synthetic material to eliminate weight and seams. It also improves the fit to the foot and provides stability.
The design is sturdier in the heel and central area to prevent deformations.
The midsole is made with the FULL DUAL PULSOR system: double phylon in different densities that add extra cushioning. In addition, it incorporates gel in the heel that absorbs impact and propels the stride. This is PULSOR technology.
The sole is made of high density DURABILITY rubber to withstand abrasion. It incorporates the STABILIS system, a piece located in the torsion area of the sole that stabilises the tread and avoids unwanted twisting. It also has FLEXO flex grooves to achieve a more natural foot strike.

Durability
High-resistance rubber that delays wear due to abrasion.
Flexo
Flexion lines system located ergonomically on the sole to offer the smoothest transition from heel to toe with each step.
Full Dual Pulsor
Double phylon system with different densities to optimize cushioning. Higher density provides greater stability, while lower density results in greater lightness. This technology provides the athlete with flexibility and better shock absorption in each step.
Pulsor
Cushioning system consisting of a gel piece that absorbs the impact of the footstep and promotes the runner's push-off.
Stabilis
This is a TPU piece located in the narrowest part of the sole to prevent improper twists between the front and back of the foot, thus achieving greater stability.
VTS
Ventilation system that allows air to enter, promotes perspiration, maintains a constant temperature, preventing the foot from overheating.
