LPT: If trail debris inside your shoe is jabbing your foot, try to brush it off, but if that doesn't work, turn your sock inside out
Today I was walking on a trail with something poking my left foot. I took my shoe off and brushed the inside with my hand as well as the outside of the sock. After a couple of failed attempts, I decided to turn the sock inside out. It worked like a champ! The detritus was probably still embedded in the sock, but the pointy part was now facing outward instead of at my foot.
