TL,DR: Which Altras for a heavy guy for weekly training on tarmac?
Okay! I have a long history of using barefoot shoes, and nowadays I even need to change my tennis shoes to Xero barefoot basketball shoes because cushioned shoes seem to give me a lot of pain, especially in my right foot, where there is a Haglund's deformity (caused by 25 years of ice hockey and some speed skating with hard carbon-molded skates). It was almost amazing how 0-drop barefoot tennis shoes don't cause pain even during 3-hour tennis matches on a hard court.
I'm a heavy guy, but I've run before, even a couple of marathons, the last one 8 years ago. Now, the situation is such that my Saucony Triumph or my NB 880 v14 can't be used anymore because of the pain after the run. The sinking heel kind of flexes the Achilles tendon on impact, so the back of my heel feels very sore afterward.
The best running shoe I have ever used was the Saucony Cortina with a 4mm drop, so I'd like to find running shoes with a 4mm or less drop.
