Bootstraps cover feet, not legs

If it's worn on the ankle, it should encumber your feet, not your legs.

This change should also make the bootstrap actually useful; it provides the same encumbrance as a pair of cargo shorts, but provides far less of everything and can't be fitted. There's no reason to wear a bootstrap if it encumbers your legs, but if it encumbers your feet you can wear it instead of socks when you don't need the warmth.
