I've been wearing ASICS Gel-Phoenix running shoes for years. I've got a wide front foot (with bunions) and a narrow heel, and the medium width fits perfectly. The arch support is substantial but not too high. The shoe I bought is half the price of the more expensive ASICS brands, so it's a great buy for me. I never seem to see the Phoenix in stores, so was happy to find it on Amazon. I mostly walk very fast on a treadmill 6-7 days a week, and these babies hold up for years. I usually wear the sole out first.
