I have shoe size 41 and I have ordered the shoe in size 44-46. You are exactly right on the size and fit so well on thicker winter boots or sneakers. So best order one size bigger! The coatings are easy to apply, sit easy on, stay back Velcro and elastic band on the lower side. At the toe a little bag is where you reinsteckt foot. Above you can even change the size in which the fabric is drawn a little closer with the help of Velcro. They are super and recommended Waterproof well!
