I should have written a post on these a while ago. I bought a pair cheap in a sale just before Christmas, with a similar logic in mind to the X-Over shoes. However, these are a proper running shoe, but have a GoreTex liner.
Strangely the flex is slightly stiffer than the X-Overs and the sole under the fore foot is more cushioned. They share the 3D chassis with a very firm heel cup. The overall stiffness meant they required a couple of walks before they loosened up.
The lacing system is the Salomon Quicklace system with the pros and cons I outlined before. The tongue is less padded so a bit of care is needed not to over tighten.
It might seem a bit controversial to have a pair of shoes with a GTX lining. I’m not a huge fan of wet feet and I was keen to try a shoe that would keep me reasonably dry. My experience of GTX linings in my Fastpackers has been favourable. I’ve not found them particularly sweaty. I expect the Ultras to be even better as they don’t cover my ankles.
I’ve used them quite a lot for dog walks and like them. It’s good not to get wet feet. As the weather has been cool, it’s not surprising that my feet have not been sweaty. Grip is difficult to assess as I’ve not been on any demanding terrain. I suspect they will be ok, perhaps better on wet grass but worse on wet rock.
TBH, again, I see these as lowland shoes. I’ve found contouring on slopes in shoes uncomfortable compared with boots, so I’d rather use light boots in the hills. However, on gentler trails, especially in spring and autumn, I think these will be a good choice. Apologies for this seeming like a Salomon lovefest, but they do make good footwear and they fit me perfectly.
