The Merrell Chameleon Wrap Slams have done a fair few miles now, I've been wearing them either with very thin socks or with no socks at all because of the sizing problem. With socks they still squeak quite loudly so I tend to wear them only when I'm on solo walks, obviously when I'm going sockless they're a tad more partner-friendly but the range of terrain is restricted accordingly. Aside from the noise they've been fine on all sorts of non-icy terrain, they're not waterproof but are quick to dry. Grip has improved with use. They've been through the washing machine on the "sports shoes" cycle with no detectable detriment. If I had the correct size I'd wear them a lot more and in more testing places. Oddly, I find that they are a really good choice for driving - I think it's something to do with the way the heel grips the foot-well carpet.
The Salomon Exit Aeros haven't done as much mileage but have proved to be fine for casual, mainly indoor wear. I still don't trust them in the wet - the grip seems to have worsened with wear. Again, they're not waterproof but they do dry amazingly quickly. I've decided that they have too much flex for me to wear them on long dry walks so they've been relegated to the role of slippers - they see a lot of use during YHA stays. Shape-wise they do fit me well and if I did acquire any more Salomons I'm confident that they'll suit my feet, but there's no way that I'd get a model like this until they've sorted out the sole/grip problem.
I've come to the conclusion that footwear such as these items doesn't suit the outdoors stuff that I do, although the Wrap Slams have been OK for general outdoor wear. Maybe I've not tried them enough, maybe I've been expecting too much of them, but I really can't get on with them. My feet still feel better in more substantial footwear, and I feel more confident when my feet stay where I put them. That's why I keep going back to the AKU Croda GTXs.
