Size advice Compressport
First, a bit of general advice. For socks and non-compression products: choose your normal size.
For compression products: If you're between two sizes, always choose the larger size. Don't worry! You'll still benefit from the compression. Your muscles swell during exercise, and your size should allow for a certain margin to prevent a tourniquet effect and thus restricting blood flow.
