These guys must have been bored when I sent my shoes to them on a Friday (from the East coast), and got them back 10 calendar days later. I would have expected them a couple of weeks later being I sent them at the start of the climbing season. And a great job on resoling 32 yr old high-top Sportivas. I felt guilty only paying $39 (postage included)! I want these guys to run the government!

First off, don't believe everything Acopa tells you. If they tell you this shoe performs, you can take that to the bank. But to tell you to order your street size - forget it!
Everything I own for my feet from Sportiva, Kamick, Cabelas, Nike, Lowa, is a 9.5, so of coarse I that's what I ordered for the JB's.
When I got them, I could put them INSIDE my 9.5 comfortably snug Sportivas. I eventually went up to a size 11, and still, they are just a little smalller that my Sportivas, but they are comfortably snug.
The toe box on the JB's have about a 1/2" more room side to side than other shoes. The rubber was incredibly tacky and sticky right out of the box.
After reading another review about how they pop off the rock with no warning, I was really hesitant to put them on anything really smooth or real small. But after using them for a couple of weeks, I love them! Too early to tell about how they hold up, but they look to be pretty well made.
And they do smear, and edge on 5.12 climbs with confidence.
