The Les Mills x Reebok Ultra 4.0 sneaker is specifically designed to complement the fitness studio's dynamic training. Updated in black, this iteration's mesh upper has wavy synthetic eyestays, an AdaptAMove inner cage and mid-cut neoprene bootie with a bold pull tab. Co-branding is printed on the heel counter and a TPU frame offers extra stability. Its IMEVA midsole and transparent rubber outsole give cushioned support through transitions.
