Our boots are designed and made to fit you in your standard shoe size, with room for your trousers/jeans and a thick pair of socks already factored into the manufacturing process by our Master Bootmaker. They have an adjustable gusset with tightening strap and snap-fastening button, giving you more flexibility and a perfect calf fit for you every time you wear them. When selecting which size to order, a good general rule with Le Chameau boots is to go for the same size as your normal everyday shoe size
