説明The mach x2 is bolder than ever, injecting vitality into speed training. Inspired by the cielo x1 competition-grade geometric design, hoka one one has combined a super resilient peba midsole with an enlarged curved upper for a strong toe-off experience and extended the pebax® sole design for enhanced support and propulsion. This speed training shoe features a breathable, supportive knitted upper and a more stylish collar to keep you light, cool and fast during higher levels of training.
