For me though, for the ultimate in comfort, it has to be the slide Fitflop sandal, with it's Trademark ergonomic footbed. Some fab colours and upper finishes to suit all occasions and taste. For the guys out there FitFlop also do a men's casual range. Check out the FitFfop site. Also, if you're a nurse and a member of the RCN, check the RCN website for details about the discount arrangements for WardWalkers who also stock the FitFlop range.
Update: WardWalkers & Shoetique both have sales on at the moment.
