I've not worn proper cycling shoes, but have been wearing trainer type shoes without laces. However, peddle pressure is making the bottoms of my feet feel bruised all the time. Oddly, I can't use spd's due to an irrational fear of being restrained in any way what so ever. So would like to know of a nice shoe with a stiff sole that would be suitable for cycling. My budget would be up to about £70. Any recommendations for me?
