These are the "older" style of 13" quilted replacement liners from Kenetrek. They look almost the same to the new style, but are a little darker color and do not have a seam at the ankle. They can be used with many boots for added warmth.
Tired of brining the outside in? This boot scrubber from M&F Western Products is great for your entryway. Just put your boot in the scrubber and move it back and forth and the bristles do all the work.
