The Altra Timp IQ fit hits the cushioning sweet spot between the Lone Peak and Olympus, and features IQ technology. This coach-in-a-shoe provides you with live feedback on foot strike, cadence, impact rate and contact time. The Timp IQ's footbed sensor provides onboard coaching to help you improve your technique and form on-the-run. This versatile trail shoe has a 29mm stack height and 4mm outsole lugs for a comfortable ride that is ready to tackle any distance or trail condition. And Altra's PFS performance last and lower volume fit give you reduced lateral movement and a secure fit. Breathability and durability are combined in the upper with laser cutout TPU overlays and extra coverage in higher abrasion areas, like the toe box and heel cap.
