For cotton styles, a 30°C machine wash is fine, with the removable insole left in place; avoid the tumble dryer and prefer air-drying to preserve the fibres. For wool and cashmere styles, be gentle: delicate cold-water wash with a wool or silk detergent, no fabric softener, and spin limited to 600rpm max. A cashmere comb (anti-pilling) then removes any small bobbles caused by friction, before air-drying flat, away from any heat source.

Absolutely. In winter, their soft materials (cotton, wool or cashmere, depending on the style) bring warmth and cosy comfort. In summer, lighter versions such as ballet flats or espadrilles offer breathability and freedom of movement. A product designed for the whole family, all year round.
