Brambler Hunting Boot GaitersSizing Note Sizing boot gaiters can be a bit tricky. Generally, if you wear full boots (e. g. Hanwag Tatra Top GTX, Meindl Taiga GTX) and or have large feet or calves (size US 10 EU 44 and bigger) you will likely want to go with the LG. If you have smaller feet or calves (size US 9 EU 42 and smaller) or wear a lighter boot or trail shoe (e. g. Salomon Quest 4, Salewa Alp Trainer) you will want to go with the SM.
