I bought a pair of Altra running shoes back in October. I adored them and had no problems for the first few months. I then didn't get much use out them for 5 months while recovering from a broken arm. I have recently began running again and have noticed they wore out incredibly fast after picking up the amount of miles ran each day (only about 2-5 miles). This is the most comfortable shoe I have ever had and had no other problems with it but I spent way too much money on them to wear out this fast. Is there a way I can have them replaced with another Altra shoe in hopes of them staying in better shape longer? What would be your best recommendation?
