Speedcross 6

The Salomon Speedcross 6 is the go-to shoe for muddy, soft-ground ultras. Its deep chevron lugs bite into loose terrain like nothing else, and the Contagrip MA outsole sheds mud efficiently.

What It Does Well

The Speedcross excels on soft trails, forest paths, and muddy race courses. The fit is snug and precise, with a speed-lacing system that cinches down in seconds — a real advantage at aid stations when you're swapping shoes with cold, fumbling hands.

The cushioning is moderate: enough for 50K distances, but most runners find it too firm for 100-mile events. It's a specialist tool, not an all-rounder.

Where It Falls Short

Rocky terrain exposes the Speedcross's weakness. The aggressive lug pattern doesn't grip well on hard surfaces, and the lack of a rock plate means sharp stones punch through. If your race has mixed terrain, look elsewhere.

The durability is average — expect 300-400 miles before the lugs wear down significantly.

The Verdict

If your race is muddy, the Speedcross 6 is hard to beat. It's not the shoe for every ultra, but for the conditions it's designed for, nothing comes close.
