Warm and fuzzy slippers are essential attire in the Canadian autumn, and removing them to put on "outside shoes" is often inconvenient and time-consuming. Wearing your slippers outside, even for a quick trip to the mailbox at the end of the lane, can result in the unintentional tracking-in of unwanted debris. If one had slippers that were fuzzy on the bottom, and had a compatible treaddy sole whose upper layer was made of the "crow" type of velcro, one could simply step onto his outside slipper-soles, run around in the yard, and then remove the dirty soles upon re-entry. Winter soles with extra traction should also be available.-- lintkeeper2, Oct 07 2003 Great idea, I would totally buy them for autumn. Not really in the winter though; when it's snowy, the sides and tops of my shoes and ankles also get wet and snowy, so I wouldn't want to wear snowy wet shlippers inside the house. But wonderful for autumn!-- Mamamoose, Oct 07 2003 Nice - and when you come inside you have the choice of unvelcroing the 'outdoor' sole, or just velcroing a new 'indoor' sole to the bottom.[Mamamoose] I think for wet weather you'd velcro on a thick cork platform sole which would keep your comfy slippers well clear of puddles, etc.-- hippo, Oct 07 2003 Love it. Add [hippo]'s attachment and many others. Velcro stilts. Velco animal-shaped soles. Velcro spring soles. (combine the second two for the kangaroo soles, the first two for giraffe soles)-- Worldgineer, Oct 07 2003 Velcro tends to attract more than just what you want it to; maybe the soles could be strap-on instead. And the slippers could be made less bulky, to accomodate the sole, perhaps even something that could fit inside a shoe.-- nprnncbl, Oct 07 2003 halfbakery
