So, after a long series of troubleshooting Plantar Faciitis, I discovered the source was biking, while wearing my VFF's. Not walking, even walking more than 20 miles a day, but as little as a 2 mile bike ride in a pair of VFF's makes the symptoms return for at least 72 hours.
So, and this is a stretch, are there any minimalist shoe approaches to the cycling shoe? Perhaps a zero-drop heel with considerably less flex?
After a 3 mile quickie ride this morning in my very stiff Mossimo flip-flops, I'm considering making a pair of stiff-soled Huaraches or something to that effect, something was very pleasant about riding at 18-20mph with very cool feet.
But, if a quasi-open, zero-drop, and moderately stiff-soled bike shoe exists, I would love to hear about it.
P.S. I don't use clips currently. That either opens the door or closes it depending on the shoe.
