I wear street shoe size 12.5 in DC or Vans, Size 13 in Nike Or Adidas, I ordered the largest two sizes, got this in size 14 was still to small. If your buying an aggressive shoe or anything over moderate-buy 2 sizes up a 15 would of fit me right. Also they do not stretch much at all and the last is designed for thin heal and narrow foot. Ordered the NIAD VCS in sizes 14 and 15, as well as NIAD moccasym in RED size 14. Hoping their flat profile will let my feet fit in them. Thank god for Amazon Prime, with my big feet NO store carries any shoes in my size. Even went to the flagship store in NYC & they had only 5 crap beginners shoes in my size. Also, 5.10 NIADs are gym only these PRIMEAON could be used outdoor as well. While Niads are gym-only shoes, If they fit I will let ya know follow me on @Cryptodelphi on Twitter. Also live in lower 48 order from EVOLV or SCARPA for free returns. Both Make several moderate shoes in sizes 14+, Ahh La Sportiva Tarantulace is a great cheap beginner's shoe, that comes in sizes up to 16. If I was to buy ONly one shoe for Gym and outdoors, right now I think it would be the SCARPA Mid ECO Maestro Trad shoe. Really Does it all. another trad shoe to consider is evolv general, not meant for indoor, but can easily be used for it. If you wear street shoe 11 or smaller u may be able to find shoes in stores, but street shoes are 12.5 and bigger and you're really limited. Plus must larger size shoes are really ugly shoes. No, style points, but with this sport, it's about the fit & performance, not style. If I wore a size 12. a Size 14 Primeaeon would of fit. So. ill Mamoas or topo collab for smaller feet is a great starter shoe. So are the Scarpa Vapor Men's lace for indoor and outdoor. I did order size 14 in Scarpa Veloces indoor-only shoe. Also, check out YOSEMITEBUM.com don't buy new shoes when you can get the best Industry rubber & have ANY CLIMBING SHOE Re-Soled in Vibram. They also customize the Re-Soles so you can add rubber where it wasn't before.
