Created in collaboration with BOA®, Altra Timp 5 BOA® features the BOA® PerformFit™ Wrap upper, designed for optimal pressure distribution. The asymmetric upper wraps the foot tightly, reducing pressure points and improving the connection between the foot and the midsole. This results in improved power transfer and a more secure heel hold for greater efficiency. The BOA® Fit System with PerformFit™ Wrap offers scientifically proven benefits: up to 7% improvement in stability and control and 9% increase in energy efficiency.

The Altra Timp 5 BOA® also features a Vibram® Megagrip sole for unparalleled grip on wet and dry surfaces, a renewed foam compound for the Altra EGO™ MAX midsole, GaiterTrap™ for easy gaiter attachment without laces, and finally a spacious toe box and zero drop.
