Product Overview

Hydroventure 2 is an exciting update to the award-winning original. It features our proprietary single-layer eVent® breathable/waterproof upper, a fully gusseted tongue, forefoot rock plate, 2-density injected EVA midsole, and new Vibram® Megagrip outsole. A 3mm drop, 25mm x 22mm platform means the Hydroventure 2 allows for natural movement while still offering the protection you need on wet, technical trails. The 2-density injected EVA midsole is softer near the foot but more responsive on the bottom. A new Vibram® Megagrip outsole features deeper, more generously spaced lugs for ”toothier” traction in wet, muddy conditions. Hydroventure 2 now has a gaiter attachment for the Topo gaiter (sold separately) and 2 lace colors for multiple looks.

Great grip/too heavy


Awesome grip on wet rocks. Wore this on a Trail Marathon with lots of climbing on slick rocks. Never once slipped. Others were slipping like crazy. They got hot and were too heavy to race that distance in in my opinion. The grip needs to be put on your lighter shoes in my opinion.

Not Waterproof


Nice shoe, but the upper is not waterproof. I've tested by simply running tap water gently over the upper with my hand inside touching the opposite side of upper material and yes water transfers through on both shoes.

Great ! Sorry - But not really waterproof


This shoe is great in a lot of ways.....but it's not really waterproof. Water leaks in a big way through the untaped stitching in tongue area.
