Total Betrayal

Seriously Merrell? Complete removal of the features that make the Nova line what it is (was). I've had several pairs of Nova 3s, they're awesome. I thought I was a Merrell customer for life, after this though, these will probably be my last pair of Merrell shoes ever. The waterproof lining sounds like you are walking around with diapers on your feet and they don't breath anywhere nearly as well as Gore-Tex. I could wear my Nova 3's all day long and never have any moister buildup. With the exact same socks and exact same activities it's clear that this waterproofing material is totally inferior. No more Vibram, a corner stone of this type of shoe. Whatever the mix is that was used for these is seriously underwhelming. They're super slippery on random smooth surfaces. I can't image ever trying these on an actual trail with slippery rocks. That would never be a concern with Vibram. No rockplate. No gaiter strap. The fit is totally different. It's extremely frustrating buying a pair of shoes that you've trusted for years and get this level of subpar performance for the same, if not higher cost.

Disappointment
