So I have been wearing the Chameleon Stretch shoes for more than 5 years. They have been the most comfortable and durable shoes I have ever worn until recently. I wear these shoes every day through all kinds of situations from working around the yard to full blown off trail hiking. Generally I was able to get 6 months to 1 year out of them. The last pair I purchased though wore out in the heel area after only a few weeks until I had a big hole in the heel, which was quite uncomfortable. After putting some pressure on Merrell and returning the shoes they sent me a replacement. Unfortunately the replacement had the same stitching on the heel and ended up wearing out just as quickly. Now I have to search around for shoes that work for me and will last. I buy more expensive shoes because I am tough on them. Merrell used to be a sign of quality, but like all companies that get too big for their britches, they have become more concerned about profit than quality and their shoes no longer hold up. Too bad for them...too bad for us.
