I bought these new and even more pricey Merrells about 7 months ago. I have loved my previous ones and alway wear them till they drop to bits. Usually this takes a year to 18 months. These have given up the ghost after only 5 months.
Straight off they weren't nearly so water-proof as the merrells I've owned before, letting in water when walking on wet days. Also they didn't seem to offer as much grip or support as previous models.
Overall very disappointing and I think I might move away from the brand and head for a cheaper but hopefully better option.
