Got these from a company called Dirty Girl Gaiters ( yes they sell to guys too ) . Up until now I have had lots of problems with small rocks and sand getting into my shoes and causing me to frequently need to stop to empty out my shoes during a run. Maybe it’s because I don’t wear socks, not sure. However today’s first run with the gaiters was great. No more rocks and sand in my shoes. I give them a huge two thumbs up.
