How to Fit the 9.81 ETERE for Speed Hiking

Quick answer

To fit the 9.81 ETERE for speed hiking, choose a snug but not tight size, lace with a heel-lock technique, and check for minimal heel lift during a brisk walk.

How to fit the 9.81 ETERE in 4 steps

1. 1. Measure your foot length and width: Stand on a piece of paper, mark the longest toe and heel, and measure the distance. Add 0.5–1 cm (about a thumb's width) for the toe box. The 9.81 ETERE runs true to size for most, but if you're between sizes, go up for thicker socks or down for a barefoot-like feel. Check both feet; the larger foot determines your size.
2. 2. Try the shoe with intended socks: Use thin to medium technical socks you'd wear on a fast hike. The shoe's unstructured upper means it won't stretch much, so what you feel at try-on is what you get. Avoid thick socks that crowd the toe box. If your toes touch the front when standing, size up.
3. 3. Lace with a heel-lock (lace-lock) technique: After threading the laces normally, create a loop at the top eyelet, cross the laces through the opposite loops, and pull tight before tying. This locks the heel in place, reducing lift. The 9.81 ETERE's low-cut design makes this especially important. If you still feel heel slip after lacing, try a different lacing pattern or a thinner sock.
4. 4. Walk briskly on a slope or stairs: Simulate downhill motion: your foot should not slide forward. The shoe's minimal structure means it relies on your foot's natural shape, so any discomfort during this test indicates a poor fit. Repeat the test with the heel-lock lacing. If your toes jam against the front on descents, the shoe is too long or too short; try a half-size adjustment.
