Brought back for an encore this season, the Columbia Women's Bugaboot Plus Zip Omni-Tech Snow Boots have been upgraded from really warm to super warm thanks to the addition of an Omni-Heat lining. While synthetic insulation helps retain body heat, the Omni-Heat technology reflects your warmth right back at you with tiny printed silver dots. These winter boots have a durable, stylish, easy-care leather upper that works with the Omni-Tech membrane to keep water out while letting your feet breathe. The smooth zipper and faux fur detail at the top make this ankle boot easy to pull on for a quick run to the woodshed and stylish enough to wear into town. An extra layer of insulation underfoot boosts warmth and a contoured EVA insole cushions your step. The full-length Techlite shell sheds weight off the previous design and has TPU-coated leather overlays for additional durability and abrasion resistance. The non-marking Omni-Grip outsole uses big lugs and dual-density rubber to give you traction in any temperature. With the superb style and comfort that made the original Columbia Bugaboot Zip Snow Boot for women so popular, Columbia Sportswear decided to amp it up with new warmer and lighter innovations.
