Scratches on the bottom of Skinbased skis are mostly superficial and do not affect their performance. However, if the skis are used heavily and have many scratches, it may be beneficial to apply Skinbased ski waxes or mountainFLOW Quick Waxes to improve glide and conceal the scratches. The Unicoat sole can make scratches more visible, but they still do not cause any significant problems while skiing.
