I purchased these shoes in preparation for my year long backpacking venture around the world in 2009. The shoes were brilliant, lightweight for walking/trekking, comfy and strong! As I was limited on space these were the only shoes I took with me along with a pair of Merrell sandals! I would hazard a guess that I wore these shoes everyday! My trip consisted of various activities including general walking around the cities, hiking/trekking, camping, walking in rivers/seas (I know they are not waterproof) etc. They have covered hundreds of miles of trekking (including the Grand Canyon, Angels Landing), been worn on nights out and general day to day wearing. After 4 years of punishment they are now starting to look a little worse for wear, although there is still plenty of grip on the soles! Would I buy another pair........ In a heartbeat!
