Familiarity: I've put it through the wringer
Well maybe not but I love the look. You'll definitely have a bunch of people "asking" what brand they are.
Switched to the Vertical K from the Quantum and I couldn't be happier. Lower to the ground, lighter and sticky. Oh so sticky. I do a lot of rock hopping and am blown away by how well these stick to everything.
Only two problems.
The built in lace cover/gaiter makes getting to the laces a hassle. Got a knot in one and I decided to just leave it.
The smell. If you sweat a lot or ever wear them barefoot be prepared to leave them outside for awhile. Definitely couldn't sleep with them in the tent. They just don't breath well enough to allow them to dry out easily.
