Boston is a breathtakingly lightweight safety trainer that has been manufactured using a supportive TPU cage upper, that offers outstanding foot support and breathability. It has a 100% non metallic construction, including a fibreglass toecap and composite midsole. The outsole complex is a dual density EVA nitrile rubber outsole which gives abrasion resistance whilst providing exceptional shock absorption and weight reduction. All day comfort comes from an Activ-Step PU anti-fatigue comfort footbed.
