Marella Samphire Sandals 35

These are gorgeous sandals and still in great condition.
They are made out of a specially developed leather that is designed to cope with getting wet and drying out; they are machine washable and resilient to most things the outside can throw at them.  Put inside an old pillowcase to protect your machine, and wash at 30 degrees with no detergent. Allow them to dry naturally away from direct heat (no balancing on radiators!)
Great brand, from Petasil - they have light and flexible soles and come in a medium width  but are adjustable for a slimmer fit. 
RRP £44
