Title: Protects nails, but gives blisters
Review: To give some reference - I have run 6 marathons thus far and have gotten black toenails after each marathon (my toenails no longer fall off). I purchased these caps with the hope that they would prevent my toenails, which they did. However, I did end up getting some blisters where the caps ended and ran into my foot (so, at the base of my toe). Not sure I would recommend these as the blisters were pretty painful during the marathon and the toenails never bother me until AFTER the marathon is over. So whether you want to buy them or not depends on which is more important to you - no black toenails or fewer blisters.
