Merrell Moab 3 Gore-Tex Review & Sizing Guide

Published Updated

Buy Moab 3 Gore-Tex as the default starter hiking shoe for wet trails and field work where you want a Vibram outsole and a real waterproof bootie; skip it for dry summer hiking because the GTX runs hot and sweaty in heat I noticed they are far too warm in the summer months for daily wear (maybe because they are well sealed for waterproof?).

Full breakdown

Merrell Moab 3 Gore-Tex is the waterproof version of Merrell's bestselling daily hiker: classic suede-and-mesh upper, Vibram TC5+ outsole, and a Goretex bootie built for wet hiking and field photography. The Moab 3 GTX is widely considered the default beginner hiking shoe in r/hiking, with owners cross-shopping it against the non-GTX Moab 3 Waterproof when budget and weight matter I have decided I want to get the Merrell Moab 3 after trying on several different options. I am unsure if I should get the WP ones or the goretex ones. Buy it for wet trails and creek-crossing hikes; do not buy it for dry summer use, where the GTX runs hot.

FAQ

Should I pick Moab 3 Gore-Tex or the standard Moab 3 Waterproof?

Choose GTX for serious wet hiking, choose the non-GTX Waterproof for budget and lighter weight. The most direct buyer thread is from someone with ankle pronation and flat feet trying to decide, with the Waterproof on a strong sale and the GTX heavier I prefer lightweight shoes and I've heard the goretex ones are slightly heavier. I would wear them while fishing in creeks, so being able to stand in very shallow water (like 2 centimeters or so) would be important to me. For shallow standing-water use, the M-Select Dry treatment on the standard Waterproof is enough. For full-day wet trail or rainforest work, GTX justifies the weight.

Does Moab 3 GTX actually keep your feet dry in heavy rain?

Yes, but waterproof shoes always have an upper-height limit, and Moab 3 GTX is no exception. A wildlife photographer in India hiking between arid deserts and the rain-soaked Western Ghats specifically chose Moab 3 Mid GTX after Salomon Ultra GTX failed at waterproofing after one year of heavy use I have used the salomon ultra Gore tex for 2 years now but it didn't live up to its waterproofing abilities after just one year of extensive use. Buy the Mid version for rainforest work because rain down the ankle collar is the primary failure mode; skip the Low version if you expect to wade deep puddles.

Does Moab 3 GTX run hot in summer?

Yes, and the same owners who love it for cold and wet often complain about summer heat. A Moab 3 Gore-Tex Wide daily-wear owner specifically calls them too warm in summer months and is asking for a non-waterproof Moab alternative with similar feel I noticed they are far too warm in the summer months for daily wear (maybe because they are well sealed for waterproof?). Basically my feet will get too warm and sweaty after a full day. If you live in a hot, dry region, buy the non-waterproof Moab 3 Ventilator instead. If you have year-round wet weather, the warmth is a fair trade.

Is Moab 3 a good wide-foot hiking shoe?

Yes, Moab 3 is one of the best wide-foot hiking shoes still actively made, and 6E shoppers specifically anchor on it. A 12-13 6E searcher hunting for Costa Rica hiking shoes treats the Moab 3 GTX wide as the baseline they would blow out the sides of if nothing better surfaces the best I can think is just to blow out the sides of some Moab 3 gtx's so any help is greatly appreciated. For standard and wide width, the Moab 3 is a strong first hiking shoe; for 6E width you may still need to look at Hoka Anacapa or Topo Trailventure.

How should I care for Moab 3 GTX after full water ingress?

Let them air dry, avoid any direct heat source, and the Goretex membrane will continue working. A first-time hiker who submerged Moab 3 GTX Mid above the ankle on a first hike got the same advice from r/hiking. Stuff with newspaper to absorb interior water, air dry for 24-48 hours, and choose Nikwax Fabric & Leather Proof once a season to keep the suede repelling water; do not buy aerosol silicone waterproofers, which clog the membrane.
