I liked the idea of these a lot more than buying a $100 pair of boots that I'm only going to wear once or twice a year (just for ren-fest and/or halloween).  These aren't super-tough, so you will want to be careful in them...  maybe add some reinforcement if your going to be wearing them a lot or they might tear (especially wear it wraps under the foot).

Overall they are exactly what I needed for ren-fest.
