The KNX Lace Shoe fuses its leather upper to the sole without glue or solvents, using KEEN's own bonding process for a seamless connection that holds up over time. A 3mm heel-to-toe drop keeps the foot close to a natural, barefoot-like position, and at 8. 47oz the shoe stays light enough to wear from morning errands into evening plans without weighing the foot down. A no-tie stretch lace system locks in a snug fit for quick on-and-off wear, with a traditional lace option included for a different look. What Our Gearhead(R) Experts Are Saying:"I wore these through a full day of walking a city I'd never been to, and my feet never felt like they were carrying extra weight by the end. The fit stayed just as snug at hour ten as it did when I put them on."
