I run approx 20-25 miles per week and have for the past 8 years. I have run with Nike, Brooks, and New Balance but never tried Asics until January of this year (2012). I have had planter fasciitis for the past 5 years and although I now run with orthodics, the pain has never completely subsided. The first few steps out of bed in the morning were always painful, particularly in the right foot and the pain in the heel was constant all day. Six weeks after running in these shoes - no pain what so ever. It's like they were made for my feet. I didn't think I would ever be pain free again but thank goodness that I tried Asics. This is my second consecutive pair.
