STRIDER Strider Japan's Optional Parts Ski Attachment for Snow Strider Genuine, for 14-inch Includes dedicated foot steps Please see the Strider official website for installation instructions. I purchased this from an official Strider retailer last year to participate in a winter event for the Strider 14 X. Ultimately, I barely used it due to rain, so the usage time was short, but there are some skid marks on the bottom. I am also listing this on other sites, so please check for availability before purchasing.
