its bad for your boots becuase they get all gross and soggy and moldey. Trust me, i ramped for 2 weeks in the summer and my boots were fucked after. The liners like were shaped different and all hard. I had to get new boots is what im getting at. Also whoever said its not bad for skis.. its terrible, water gets into the skis and when it freezes in the winter they crack and the skis break.
