I have a nightmare with shoes. They rub all the time, wearing in new shoes fills me with terror. Getting new sandals or flip flops is a nightmare, finding a pair that won't kill me. Primark once did a good set that were foamy and didn't rub at all. They have, of course, not sold them since.
In Asda today I had a look through what was around and decided to give these a chance. They're the best hope I have. Wish me luck.
