The three buttons are just for show on Tundra’s “Frieda” pile-lined boot. There’s a full-length side zipper opening on the inner side of the 10” glove-soft leather shaft, which is lined with plush faux fur. The lightweight TPR treaded outsole is designed for good traction. Whole sizes 6 to 11 in XW. Seasonal item: some sizes may sell out early; check pulldown for current availability.
