When I run I have problems with supination when walking. This causes my foot to naturally roll outwards, causing my shoes to wear out quickly on the outside of the heel. I'm in the endless search for running shoes that don't wear out as quickly in this area. I've read some professional reviews that suggest this shoe (along with the high arch insole) handles this issue well. heel and exposed the midsole. Only the rubber of the sole doesn't seem to be very "hard". I run about 15 miles a week. and it lasted about 6 weeks! So if you want to solve this problem too. Keep searching. On the other hand. if you don't have this problem. it is a good running shoe with a particularly comfortable upper and a good lacing system.
