In Krav Maga I caught my finger on the mat causing blood to come out from under my toenail. The instructor advised me to wear wrestling shoes in the future. I bought these shoes a size 12.5 because I read they run small and I usually wear a 12. They fit well. Also, my toes will be sore and red from hitting the mat, and shoes should help with that, too. I currently wear them at home and they help relieve pain from flexing my toes while walking.
