Bought these for my wife, she's had several pairs of Mary Jane crocs before, the only difference with these is the fixed back strap and a slightly slimmer design. Sizing is perfect, she's usually 3 1/2 UK size. The material is quite flexible and soft so hasn't taken much wearing in. Good tread on the soles so not slippy on wet surfaces as her old ones had become. Perfect for round the house, garden and particularly when camping.
