I can't wear flip flops because I have a high instep. I used to take a pair of cheap crocs for going to the pool, much to my daughter's disgust, but last year I picked up a pair of sliders in Lidl and they are so comfortable. I ended up wearing them round the campsite.
I have a ridiculous phobia about flip flops. I have tried to wear them but its just no good. I can actually have to psych myself up just to put them on. Wish I could wear them as there are so many lovely designs.
