ALTRA TIMP 6 GTX
The ALTRA Timp 6 GTX is a technical waterproof trail shoe for runners tackling rain, mud and wet trails without compromising on comfort and efficiency over long distances. It combines high cushioning, excellent grip and natural zero-drop geometry, so you can run with confidence and control when the terrain becomes slippery.
GORE-TEX Invisible Fit – Lightweight waterproof protection
The GORE-TEX Invisible Fit membrane is designed to provide waterproof protection with a cleaner fit feel. Rather than feeling a bulky internal layer, this technology integrates more smoothly with the upper, helping the shoe remain more comfortable and natural underfoot. It also provides waterproof protection and breathability to manage heat when the intensity rises.
85% RPET Upper – Durability with more responsible materials
The upper is specified as containing 85% RPET (recycled polyester), meaning a high proportion of recycled polyester is used in the fabric. In practical terms, this supports a more responsible product without changing the objective: a secure fit, durability for everyday trail use and comfort over extended periods.
Altra EGO™ MAX – Cushioning & controlled bounce
The Altra EGO™ MAX midsole delivers a high-cushioning feel. It absorbs impact from rocks and hard ground, reducing the load transferred to the knees and hips. At the same time, it maintains a controlled rebound so the ride does not become unstable on uneven terrain. It is the choice for runners seeking ultra-distance comfort alongside predictable control.
Vibram® Megagrip – Grip when the terrain is wet
The Vibram® Megagrip outsole uses a premium compound known for grip on wet rocks, roots and slippery surfaces. For the Timp 6 GTX, ALTRA specifies a redesigned Megagrip outsole, aimed at providing more confident purchase on the trail and better control during changes of direction, especially when the ground is muddy or broken.
Zero Drop™ & FootShape™ Standard – Natural alignment and toe room
With a 0 mm drop, the platform maintains more natural alignment, with the heel and forefoot at the same height. This helps many runners experience a more grounded feel and stability on the trail. The FootShape™ Standard provides room in the forefoot for the toes to spread more naturally, which often improves balance on technical terrain.
