These are suuuuper tacky. I've taken them on some rough roads and I've taken a couple small chunks out of the rubber, but they've held strong and rail corners I wouldn't imagine on other tires I've used.
I have a wide forefoot and a narrow ankle, so finding shoes that fit can be tough. These are perfect for me, heel stays nice and snug without cramping up my forefoot. Super stiff, light, and look gooooooood!
