4:Sys midsole provides cushioning in key areas for a faster foot strike, improved speed and greater control.
To benefit runners, Hi-Tec developed the 4:Sys midsole to provide more cushioning and support where it’s it most needed.
By supporting high pressure areas of the foot, including the big toe and the role it plays in balance stability and forward propulsion Hi-Tec has been able to enhance the 4 critical phases to running which are the heel strike, mid foot stance, forefoot and toe-off.
Cushioning the toe-off area spreads impact energy and returns it to allow for a stronger spring into the next step. Greater cushioning and energy return in the forefoot area helps to promote forward motion. Denser materials in the midfoot area offer more support while advanced cushioning and shock absorption in the heel area with the softest density in the centre reflects the highest pressure zone during heel strike for increased comfort when running.
These enhancements combine to deliver more efficiency to the wearer by allowing the foot to move naturally by reflecting the characteristics of the bare foot.
