The Topo shoe line offers an alternative to the Altra with its wide toe box. I've had 2 pairs and destroyed both in less than 3 months (50km a month). I got 6 months from Merrill and 4 months from Altra Escalante. Much of the rapid wear and tear is caused by pronation, which deforms the floor and causes ankle pain after what could be considered a slump. The shoe is light and designed for a good run, but not strong enough for road runs of 5 miles or more.
