ALTRA TIMP 6 GTX
The ALTRA Timp 6 GTX is a technical waterproof trail shoe for runners tackling rain, mud and wet trails without sacrificing 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 waterproofing with a cleaner fit feel. Rather than feeling a thick inner layer, this technology integrates more smoothly with the upper, helping the shoe remain more comfortable and feel more natural underfoot. It also provides waterproof protection and breathability to manage heat as intensity increases.
85% RPET Upper – Durability with more responsible materials
The upper is specified as 85% RPET (recycled polyester), meaning a high proportion of recycled polyester in the fabric. In practice, 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 controlled rebound so foot strike 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, designed to provide more secure bite on the trail and improved control when changing direction, particularly when the ground is muddy or uneven.
Zero Drop™ & FootShape™ Standard – Natural positioning 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 feel more grounded and stable 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.
