Both are Salomon models, but lasts differ. Speedcross 6 is labeled Runs Small (Half up vs casual shoes; TTS (or half down) only for race lockdown). XT-6 is Runs Small (TTS length for narrow/average trail fit; half up for wide feet, thick socks, or lifestyle comfort).
Speedcross 6 is precise: TTS length for a trail shoe but snug versus casual sneakers. Half up is common for hiking, thick socks, or all-day comfort; racers sometimes stay TTS or even half down for lockdown. Prefer Salomon Wide over jumping a full size — Partial because performance vs hiking advice splits.
XT-6 uses a performance trail last with a tight SensiFit wrap — length can read short/narrow versus street sneakers. Many lifestyle wearers go half a size up; narrow feet chasing a locked trail fit can stay TTS. Sock thickness and downhill toe room matter as much as the label.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.

| Width | Narrow aggressive trail fit; wide SKUs exist — prefer width over oversizing length | Precision SensiFit — narrow midfoot; thick trail socks often need half up |
