I think if they are comfortable and feel great you should definitely consider them for gear -- and maybe test run them as fashion sneakers as well with a few outfits before they go on a trail.
Here's where the sneakers as a fashion trend thing gets really tricky for me personally. Sneakers are so so tribal. Both the style (retro, hi-top, slip on, etc.) and brand communicate things about the wearer completely separately from how they look visually. Also these associations change over time. For example when I was a teen, Cons were skate shoes, but Vans were dirt bike shoes, and the two tribes tended not to get along. Keds for me had little girl and 60's bombshell associations, until Taylor Swift became their spokesmodel, and now they have Taylor Swift associations. Nike was linked with sweatshops, but now it maybe isn't? Toms were frumpy until they were hipster. Sketchers....I associate with tweens? Maybe I'm over-thinking it, but this is why it took me three months to buy a pair of fashion sneakers recently....
