Merino Wool Running Socks

Running socks: why merino wool

Our models share the same composition: 50% merino wool, 30% nylon, 15% acrylic and 5% spandex. Wool absorbs moisture and wicks away sweat. Its keratin structure inhibits certain bacteria, which reduces odors after exercise compared to synthetic fibers. Nylon and spandex provide durability and elasticity. All pairs have an anatomical fit. They are designed in France by runners.

CrossRun Low or CrossRun Mid: low or mid-calf?

The CrossRun Low is a 15 g ankle sock in size 39/41. An airy pique mesh knit covers the foot. An elastic band holds the midfoot, a heel tab protects the Achilles tendon and a single toe seam eliminates friction. It's the pair for hot days and intense workouts.

The CrossRun Mid has a mid-calf height and weighs 45 g. Its cushioning is reinforced at the heel and toes to absorb impact. The knit changes depending on the zones to support the foot and keep it ventilated. Wool retains heat: it's the pair for running in all weather conditions.

Trail socks: which model for the trails

In trail running, the terrain changes constantly and outings last longer. The CrossRun Mid, more covering and cushioned at the heel as well as the toes, is the best choice for trail socks and ultras. The CrossRun Low is suitable for rolling paths when it's hot. For long outings, add a hydration belt and find the rest of the outfit in the trail clothing.

Which size to choose

The models are available in 4 sizes: 36/38, 39/41, 42/44 and 45/47. Choose the size that fits your running shoe size. The pairs are unisex: you can also find them in the men's running socks. If the size doesn't fit, exchanges are free within 30 days.

Complete your equipment

A good pair of socks goes with bottoms that don't chafe. See our men's shorts and cycling shorts and our women's shorts and cycling shorts. Handheld bottles, gloves, bags and race bibs are gathered in the running equipment.

Frequently Asked Questions About the Socks Collection

Why choose merino wool running socks?

Merino wool absorbs moisture and wicks away sweat, keeping feet drier. Its keratin structure inhibits certain bacteria and limits post-exercise odors more effectively than synthetic fibers alone. At Bodycross, it makes up 50% of the composition of the CrossRun Low and CrossRun Mid, with nylon and spandex for durability and stretch.

What is the difference between the CrossRun Low and the CrossRun Mid?

The CrossRun Low is a 15 g ankle sock, ventilated with a mesh knit on the foot, designed for summer and intense workouts. The CrossRun Mid is mid-cut, weighs 45 g, and adds enhanced cushioning to the heel and toes. It can be worn in all weather. Both are made of merino wool.

What trail socks should I wear for a long run?

Choose the CrossRun Mid. Its mid-height upper covers more of the foot, while the cushioning in the heel and toe absorbs impact and reduces chafing over time. The zoned knit keeps your foot secure while allowing ventilation. Merino wool retains warmth when temperatures drop at altitude or later in the day.

Are Bodycross socks unisex?

Yes. The CrossRun Low and CrossRun Mid are designed for men and women, with an anatomical fit. They are available in 4 sizes, from 36/38 to 45/47, covering both small and large shoe sizes. The only difference between the two models is the color options: 5 for the Low, 7 for the Mid.

Can you run in wool socks in the summer?

Yes, if the sock is thin and breathable. The CrossRun Low weighs just 15 g in size 39/41, and its pique mesh knit allows air to circulate around the foot. The merino wool absorbs sweat instead of holding it against the skin. This keeps your foot cool and dry on summer runs.
