Since I’m not living in Belgium anymore but in the South of France, the need for real high and thick socks is less, so I started thinking about an alternative and I started knitting ankle socks. These are not as high as normal but which will keep your feet at the perfect temperature in sneakers or other shoes in the provencal climate.

(to be comfortable, socks should fit really snugly: allow about 2 cm negative ease both in foot circumference and instep length)
