In general they would be used for low level forest walks, walks to the pub, sometimes on road or through the woods and just general pottering about. I have boots for more technical walking that doesn’t involve jeans
Speedcross 3 would be a bad choice for this. They are a fell running / adverse conditions running shoe. If you need to go Salomon look at the Wings range or the XA range. They won’t look as rad down the pub, but they will be more comfortable.
If you contact Salomon themselves they should echo this, as should any decent shop.
I got a free pair of Speedcross 3s to try a while back and I didn’t really like them at all, not even for their intended purpose of trail running. For standing about and general bimbling, not very nice either.
Brooks Cascadia 10 and Asics Fuji are much better trail running shoes, and they are more comfortable for general walking and wearing.
