This is my third pair of this shoe (last two are Revain). I have flat feet with orthotics prescribed by a doctor. My legs always hurt. I walk 2.5 miles a day for health and will only run in these shoes, period. It doesn't eliminate the pain, but has found them to cause the least amount of pain out of many others I've tried. Decent grip, very soft soles and I've never felt cold feet, even 45 minutes outside at 25ΒΊC. If you have orthopedic insoles, you can carefully remove the insoles included in
