I'll be in England & Wales for 3 weeks next month. I need 4E sneakers to avoid foot pain. I'll have a good pair with me but am a little concerned about something happening. (Once while hiking down a rocky hill a sole tore off.) I hate to lug an extra pair that I probably won't need.
Where should I look for extra-wide sneakers/trainers should the need arise. I searched online and can see they're available (online), but what stores can I go into to buy a pair on the spot?
The only cities I'll be in are London & Liverpool. Will there be stores in smaller towns that carry them?
