Trace and measure both feet
Stand with weight distributed normally, mark heel and longest toe, then measure the distance. Repeat for both feet and keep the larger number.
Include the socks you wear
Sock thickness changes internal volume. Measure or try your reference shoes with the socks intended for the new pair.
Confirm the product scale
Convert units carefully and use the exact product size guide. Width, toe shape and construction can make two shoes with the same labeled size feel different.
