I've only had these flip-flops for a few days & I can honestly say they are the most comfortable I have ever worn. The foot bed is nice & soft,but sturdily made. My feet do not slip out as the material grips them naturally. I expect they should last me for a long time as I mainly use them around the house & short walks to the corner shop. I can highly recommend them for the price I paid,under £20 including next day delivery. Very happy with my purchase.
