I have a teen boy who just spends summer in socks and trainers. It seems hot and a massive fag to wear socks all the time. So I look for sandals every year for him but they always seem kind of awful selection wise.
I've tried giving espadrilles type shoes to wear without socks but "they rub". I think flip flops would be a similar no go because of toe posts even if they were the coolest ever pair.
Am I just looking in the wrong places?
