Could be there's still 'mould release agent' on the rubber making it a bit slippery. I guess these shoes are never going to be brilliant on hard wet surfaces because the pointed studs give you less contact surface area, compared with, say, x-talons, mudrocs or even roclites with their flat studs.

Used to have a pair of 270s but found them very unstable - heel going over to either side so much that I wore down the seams at the heal (still managed to get them exchanged though ). Any idea whether the 272 are an improvement in this respect? - could do with a shoe like this again for the mud.
