My first TOJ was in calf and it still isn't broken in well after all this time. It's also a bit too tight Hoping the next calf thing is comfortable enough to wear daily for a while when it eventually finishes.
The lambskin is really, really tough. I TRASH my red every weekend and it's thinner and less resilient than black. No scuff marks yet. My black lamb endured me skidding down a pavement path after spraining an ankle. Again no marks. Water will do nothing.
