I mean for example if you normally take a size 10 like I do, then buy Salomon in a size 11, one size larger
Do you mean for Salomon to get a bigger size? ie TNF 8 = S 9?
I'm on my second pair of X Ultra 3's at the moment. Only on a second pair as I completely trashed my first pair doing DIY and got paint all over them. The sole was still in great shape after a good 2 years of wearing pretty much every day. My North Face lasted less than half that before i'd completely worn through the sole especially on the heel. The Salomons also give a lot better grip crossing wet sloping muddy fields walking the dog whilst wearing them.
I got Karrimor shoes recently and they haven’t lasted well.
