I have used Asics for years; either Nimbus or Kayano - both are fine, but I always seem to get a burning sensation under my toes on long runs (12+). I should not that I have always had this pain, whether running in Nike's, Saucony, etc., always seems to come on in the 10-14 miles range. I visited a podiatrist thinking I had nueromas - didn't. He gave me some metatarsal pads - I tried these, but they were so uncomfortable I could never get used to them - I prefered the burning sensation to it. I am hoping to find some shoes with better forefront cushioning to help delay the on-set of this pain. Any suggestions?
