About 3/4 weeks ago I bought some Karrimor Traveller Supa Men's Walking Shoes and I've noticed that the insoles (the red bit on the picture) are starting to move around inside the the shoe. After a few hours of wearing them, the insoles have slipped back away from the front, leaving about an inch at the toes. So far I've just been wearing them with light cotton socks, but tied quite tight.
Is there anything I can try to stop this? Should I try to glue them back down, or is there a better way to stop this?
I'd rather not have to try and return them, the store's a bit out of my way, and I got them on sale.
