hi salsabike,
do you find the sizings of the Sugoi botties are accurate... I've looked at the sizing chart on your link for the booties, I wear a size 39 shimano cycling shoe and a size 7-7.5 shoe. Do you think it would fit if I got a pair of size S (7-8.5/40-42) booties.
A friend bought a pair of booties (not Sugoi) from a UK site, following the size on the charts, and they were really a size too small. I like to avoid having to do returns when possible.
