I'm suspicious that this is an attempt at advertising through the back door - especially as Biomike seems to have signed up to Arrse to make this post but I'm interested in the product and I need new running shoes so I'll engage in conversation.
I have a number of concerns about Five Fingers:
Fitting, I have wide feet and short big toe or long little toe so I'm concerned that they just would not fit. I've only ever seen them online never in a real shop.
Hygiene, I need to wear socks. If I wear shoes without they start to honk in very short order. It may be a fashion crime but I have to wear socks with boat shoes and walking sandals.
Comfort, I also find that running without socks is usually blister inducing.
Mrs BA has been recommended to wear minimalist running shoes - do these qualify?
