In reply to DAVE_BRAIN:
i seen your comment about the shamans being chunky and totally disagreed!
i have had a pair for a few months and they are fantastic!
they are aggresive, good edge, good heel hooking capabilities, sticky rubber, nice fit, velcro closure is good makes it even tighter, toe box is amazing!
these are the comfiest high end shoes i have ever put on my feet! i forces your feet into that crimped position but as the shoes is shaped that way it fits and isnt painful
the down sides, i find when i boulder these shoes get really hot and the arch under the ball of the foot "the love bump" disappears which means the dead space it got rid of is back (they would benefit from a p3 type idea on the solutions), this isnt a big issue i just take a 10min break pop it back to its original shape and let it cool down and re harden.
now about the clumpy thing - there does seem to be a lot of rubber on the bottom but its not really when you compare it to most shoe i think the rubber is just slightly harder and that why, it just needs wearing in! these shoes could be a little more sensitive but then that would also decrease there lifespan.
sizing can be a killer if you get it wrong, im a uk size 10 and i got a 9 but could probably have got 8.5 as they have stretched a little.
dont cancel these out because of what someone else has said, give them a go and see what you think, you put them on and they could be your dream shoe
