These shoes are excellent. The rubber is pretty good, the leather/anti-stretch has the benefits of synthetic and leather which is sweet (they're breathable, don't get smelly as quick, also don't stretch a lot). I wear a 10 street shoe, 7.5 in Mad Rock Flash, 9 in Five Ten Dragon, 8 in Five Ten Anasazi, and 39.0 in these and they're awesome. The fit is great, no dead space in my heel. I might add that the heels on these are absolutely bomber. I was using Five Ten Dragons as my main shoes and was climbing a heel-hook heavy bouldering route, then tried these on for the third time and crushed it. Another area these excel: CRACK! If you're looking for a foot jam in a narrow crack these work wonders. The aggressive toe makes it easy to slip in and the sticky rubber makes it hard to pop out. The toe has a pretty nice coat of rubber on it so they will probably last a good amount of time without holes in them compared to some other shoes. At the price I paid (64.48) these shoes are a steal. I'll probably end up buying them again at full price when they wear out, 'cause they're worth that. A couple of very very very small flaws: They dye your feet a little bit red, and the tongue is a little odd to get seated right under the laces for the first few wears. After the break-in, they're incredible shoes.
