shoes r-310

sub55

could rather do with some new shoes. been looking around on the web and quite fancy the shimano sh - r310 .
but cant find anywhere that has them in stock. must also have the facility for custom fit technology. can anybody point me in the right direction? pleeeeease.
whilst i`m here ,has anybody got a pair and what are they like.
