The weight will vary by the type of skiing. Generally, downhill ski boots for men weigh 13 pounds, while downhill ski boots for women weigh approximately 11 pounds. Downhill ski boots for children typically weigh 8 pounds, though the range is much larger due to variations in size.
Nordic ski boots, used for cross country skiing, tend to weigh much less because cross country skiing is far less dynamic than downhill skiing, and therefore requires less boot to support the skier. Generally, Nordic ski boots for men weigh around or above 2.5 pounds. Nordic ski boots for women weigh a little more, at around 2.8 pounds.
