I was tired of ruining my pretty shoes at the gym so I decided to give it a try. They are not as soft as other aggressive shoes. And the latter, and the rubber is tougher. But when I climb more than 2 hours in the gym it helps. Yes, the sizes do not match, although each manufacturer has different sizes. These are just great shoes for the price. I would happily pay twice as much, but I'm glad I didn't. For reference, I have these 12 women/11 men and they fit perfectly. I wear 42.5 La Sportiva Otaki, 43.5 Scarpa Instict and 44.5/11 Herren Evolv Oracle.
