Great for Trail Run Shoes
Used these for a couple adventure races and hikes through areas full of poison oak. They work really well, but as many echo below they are small and designed to be used with hiking/trail run shoes. I have been able to fit pants under them just fine. Size 11.5 shoe and purchased the L/XL. Also purchased the L/XL for my fiancé who wears a woman size 9, which was also a good fit. Solid OR construction and seem super durable. Just make sure to close up the velcro when washing, otherwise they will stick to everything else in the wash...tearing the crap out of light merino shirts! Darn it!
