I've had another pair of Nike Frees([[ASIN:B00D8J635G Nike Men's Free 5.0+ Dk Mc Grn/Blk/Mc Grn/Pr Pltnm Running Shoe 11.5 Men US]]) that have lasted me through climbing, river rafting, basketball, and more without deteriorating at all. Since I liked them so much, I decided to try these as a second pair. As I love the way they look, I've treated them well - they've only been used lightly for walking and some running (compared to the abuse the other's have been through). Unfortunately, they have already started to fall apart. They are VERY comfortable to wear, but for the cost of them I would not have expected parts of the soles to fall off from casual use (see pictures).
