I ordered both a 13M and a 14M for different hiking boots. The sizes are very accurate. The insoles are substantial and appear to 'break-in' quickly ... no need to heat them in the oven to speedup the molding. I don't know if it is possible to order 14 and cut it down to 13. It might make a messy cut. They are quite comfortable.
