Familiarity: I've put it through the wringer
After almost a full year with my muiras I can honestly say that I don't believe there is a better climbing shoe in the world. The rubber is perfect. After 7 months of use I had to send them in for resole. I thought that was pretty impressive though considering the amount of time I spend climbing. . .( at least 4 days a week, 1/2 of the time at the gym). After resole they are like new again and I couldn't be more thrilled.
After I got the muiras I was so impressed I got the Muira VS and the Katanas. All three are great shoes but the muira is by far my favorite. I climb a ton of friction routes and slab routes and this is my go to shoe for those climbs as well as face climbs. And it's a great shoe for overhung routes too even though since acquiring the Muira VS I've switched to those for the most overhung routes. As for sizing I sized two full sizes down. The fit is really tight but they are comfortable and they feel like they were made for my feet. I would recommend sizing 2 and a half sizes down for most people though because I have very wide feet. Just deal with the pain for a month or so and you will have the best shoe you've ever slid your foot into.
