La Sportiva Boulder
The Boulder has been discontinued. If you're looking for something new, check out the best approach shoes for 2024.
Great so long as you never intend to actually use them. I had a pair, tested them on some local crags and managed to climb up to French 6a no probs (and I don't do a lot better with full rock shoes on), and then headed off to some big walls, which I imagine is what they were designed for. Two hours into use the toes opened up, and two days later they were held together with Duck Tape. My partner's 5-year-old Vans Skateboard shoes faired much better. Only good news was that La Sportiva made no argument and gave me a full refund. I got the impression I was not the first to complain.
P.S. I also saw maybe five others in the camp trying to repair theirs as well....i.e. it is not that I had a bad sample.
Good luck.
