I had a pair of Merrells that the sole separated on after a little over a year of almost every day use. They were comfortable up until then, but I won't be buying any more Merrell shoes, my Keens are just as comfortable but have held up a lot better. A warranty is great, but I'd rather have a pair of shoes that held up worth a damn. Sole separation issues seem to be pretty common with Merrells...easier just to avoid them altogether IMO
