Women’s One 2.5


Show Size Chart


Now back with sexy new color updates, the One 2.5 connects you to your run and to the ground beneath your feet. Weighing in at only 6.3 ounces and with only 23mm of stack height, the One is the lightest and lowest profile shoe in Altra's lineup. But a lighter and lower shoe doesn’t mean less comfort. Thanks to a plush A-Bound™ layer that sits directly underfoot, you get impact reduction and energy return in each stride, essentially like a layer of bouncy ball between the road and your feet! The One 2.5 also features lightweight flexibility via a super light InnerFlex™ midsole. And with the classic Altra FootShape™ toe box and a Zero Drop™ platform, your feet can feel natural support while still being able to do their thing.
