I wish 5:10s were basically my Merrell walking shoes with their stealth rubber.
5:10’s are pretty bloody awful on all the metrics apart from the most important one: sticking to flats. But in every other measure my walking shoes win hands down – they look better, they’re (way) more comfortable, they’re cooler in the summer, warmer in the winter (considerably so – combo of them + brigdale socks and I’ll happily hike for 8 or 9 hours in deep snow), they never stink after wearing them for a solid week and, importantly, they dry out overnight (whereas unless they’re propped upside down on radiators and/or stuffed full of newspaper my 5:10s can hold onto water for more than a week).
There’s absolutely a gap in the market for much better quality.
