Sole Footbeds

I bought a pair of Sole footbeds last summer after I got painful plantar fasciitis, which lasted about a week and best I can tell was from excessive calf raises (one of my other experiments). I choose the Sole over Superfeet since they can be heat molded to your foot. Sole has a satisfaction guarantee too which is nice. Not sure about Superfeet. The shop where I bought them cut them to for my Sidis and put them in the oven for molding, all at no charge. They screwed them up several times, first cutting them too short, then too long, so they rippled in the shoe. But two pairs later they finally got them right, sort of. The footbeds reduce the volume in the shoe and in my case I almost needed to move up a shoe size. Lately, the left footbed is pushing hard on my arch, such that is uncomfortable. I examined both footbeds and the left has a higher arch. I have no idea why it's just a problem now. Anyway I'm going to try to reheat them (200F for 2 minutes) and get the arch lower. If not I'll try the Superfeet.
