Ankle socks with a grip sole and an open back, cut for a studio floor. The grip is the whole point: on a polished reformer or a wooden barre floor, a plain cotton sock slides at exactly the moment you need it not to.

These work for pilates, barre, ballet, dance and gym floor work, which is why people find them searching for non-slip yoga socks, backless grip socks for pilates, or anti-slip ballet socks for adults. Combed cotton means they breathe through a full class instead of turning damp in the first ten minutes.

The details

• Material: combed cotton
• Sole: anti-slip grip
• Cut: ankle height, backless
• Toes: closed, not finger-separated
• Properties listed: non-slip, anti-pilling, no shrink, antistatic, high elasticity
• Size: EUR 35-40 (US 4.5-8.5)
• Sixteen colour options across two styles

Choosing a size

One size covers EUR 35 to 40, which is roughly US women's 4.5 to 8.5. The knit stretches across that whole band. If your foot is at the very top of it, expect the ankle cuff to sit lower than it does in the photographs.

Care

Machine wash cool, inside out, and hang to dry. Never tumble dry or iron the sole — heat melts the grip pattern flat, and a grip sock without grip is just a sock.
