Comfortable Shoes

I mentioned this earlier, but my calf muscle is giving me grief at the moment.  And these moments seem to occur regularly.  I just can't seem to get it right.  And just after I think it's all good, then I do something which makes it starts hurting again (this time it was because I went running using the "barefoot" style - landing on the balls of my feet.  It's supposed to be better for the knees, obviously it isn't good for the calf).  Anyway, today I wore high heals at work for the first time in a while and they weren't good at all...  The calf is hurting again (not that it got better from last week)!  So today I'm going to be grateful for comfortable shoes.  I have quite a number (and some have a relatively high heel).  I just wish I'd worn them today.
