A combination of skis and skates. One size fits all. Fits into any bag: extremely light and small. Highly durable fibreglass reinforced material. Metal ski edges enable easy stopping. The heel brake lets you slow down. Use them for downhill, in snowparks, through forest trails, or sledging hills. 1) oil the edges after the season so that they do not rust 2) You can also wax the bottom of snow feet, the same way as skis or snowboards.
