Gel placement at the heel absorbs impact shock and gives exceptional underfoot cushioning, while the forefoot section encourages forward propelling energy return, accelerating you towards your next PB. The top cover Merrymesh ensures no slippage and breathable perforations allow air to circulate so your feet remain cool. The anatomical shape and dual-density structure ensure long-lasting support and vertical comfort.
