The asymmetrical lacing system increases the ability to customize the fit of the boot. Using the Crispi exclusive EFX midsole and a VIBRAM Megagrip outsole, along with Crispi'smost versatile 3-flex board last the Briksdal MTN GTX boot comfortably supports your feet and lower legs for those long, heavy pack-outs.
