tlminh

I have flat flat pancake feet. Associated with this is a wide midfoot

I currently wear some pearl izumi MTB shoes but after 5 or 6 miles, there is pain along the lateral side of my feet, right around the head of the 5th metatarsal. Not plantar fasciitis from flat feet, but pain from the shoe squeezing the foot (sorry for med terms, I'm a family physician)

I've tried numerous shoes at LBS but all they had was specialized and shimano. All hurt around the same area, with and without insoles. I've tried loosening the laces, no improvement

Any help? What else should I try?

(PS, I also had this issue with my hockey skates and it was never resolved, ie every skate I have worn over the past 10 years have always given me some amount of pain)
