It has been a few months since my review and I have been surprised by a number of negative experiences from others: I now own 4 pairs of Endorphin Speed2s, all bought on sale for $70 and $85. All men are a size 13 and I'm 6'1", 210 pounds, 79 years old and run 30-40 miles a week. I've only worn two pairs for about 20 miles to test them out (great) and put them away .Two pairs now have over 100 miles each.They are all comfortable,very well padded and return energy quickly,stable and hassle…
