I suffer with plantar fasciitis and nearly all shoes rub me. I have a cut in my ankle as the adidas gazelle Trainers tongue has rubbed me 
These sandals
Are so comfy. I've worn them around the house for 2 days and haven't had a twinge, I'm about to wear them out and about today. But had to recommend. I might even buy in the blue too as I couldn't decide on a colour.
