Hey guys! I'm going on a trip in a few weeks with my geology program, and we're going to be digging up some quartz at a quartz mine while we're there. I was thinking of wearing my NB minimus trails, but one of my professors was telling me that the quartz is very sharp, and that I'll at least want a shoe that has fabric that covers my ankles, since the quartz can cut like glass. Any ideas on some good minimalist boots that will fit my need? Or should I just buy some cheapo ones and throw them away after the trip?
