Salomon X Ultra 4 GTX Boot Review (2026)

By Grant — Last updated 2026-07-03 — hiking-boots

Grant's Verdict

10/10 — Best in Class

Salomon X Ultra 4 GTX is the benchmark for technical day and overnight hiking footwear. The Contagrip MA outsole provides reliable grip on wet rock, muddy trail, and loose scree — and the GORE-TEX waterproof membrane keeps feet dry without the breathability sacrifice of older waterproof boots.

Pros & Cons

Pros

  • Contagrip MA outsole — the most versatile single-sole for mixed terrain
  • GORE-TEX Extended Comfort waterproofing with better breathability than standard GORE-TEX
  • 1 lb 11 oz — light for a full waterproof boot

Cons

  • GORE-TEX becomes uncomfortable when interior temperature exceeds 75°F — not for hot dry conditions

The Detailed Breakdown

Contagrip MA

Contagrip MA (Multi Application) uses two rubber compounds in one outsole — a harder rubber for wear resistance on the heel and a softer, stickier compound under the forefoot for wet rock friction. Most boots use a single compound optimized for either durability or grip. The dual-compound design is why the X Ultra 4 GTX outperforms competitors across all terrain types.

Break-In Period

Salomon's Quicklace system eliminates traditional break-in at the tongue. The boot softens at the heel cup in 5-10 miles. Apply a light application of Aquaseal on the toe rand before the first wet crossing to extend waterproofing durability at the most abrasion-prone point.

Grant's Final Take

Buy these boots. They're the correct technical hiking boot for 90% of hikers in 90% of conditions.

Frequently Asked Questions

Men's vs. Women's?
Women's X Ultra 4 GTX uses a narrower last and adjusted heel pocket — don't buy men's in a smaller size to save cost.
How long do they last?
600-800 miles with proper care. Resole when Contagrip depth reaches 2mm (visible wear indicator on the heel).
