The micro crew height is perfect with my low hikers, about 6 inches showing above the collar with no gap. They stay put too, no slipping down into the shoe even on steep descents.

Wore these on a rocky 8-mile loop and didn't get a single blister. The performance fit really does keep them from slipping down into my boots, and they sit right about 6 inches above my low hikers like the description says.

Wore these on a six-mile trail day and the performance fit really held — no bunching or slipping inside my boots. Only gripe is they run a touch thin for cold mornings, but for warm-weather hiking they're solid.
