Koolaburra Swami Chestnut Slipper at Robert Frost Fine Footwear and Frostshoes.com. Swami has a great slipper feel, with a fur cuff and Aussie braid. Your feet will feel great, and theyÆll look great too. The Swami has the same cushy EVA sole as the Classic boots, and removable Merino shearling insoles for a long, prosperous life. Koolaburra runs a half size small, we suggest buying a 12 if your size is 11.5 and so on. Koolaburra Swami Chestnut Slipper is available at Robert Frost Fine Footwear and Frostshoes.com.
