Cross-country skiers are likely to love the ABH20 Water Walking Skis. Created by Slovenian designer Bostjan Antoncic, these are more or less literal cross-country water skis. Antoncic's design allows you to ski on water without the need for a boat. Your pace won't be as fast as if you were being towed behind a watercraft, however, but the ABH20 Water Walking Skis aren't about speed.
Instead, these skis are all about scoring a great workout. They engage your arms, legs and core to give you a workout similar to cross-country skiing, albeit without the snow. You won't go very fast, but you will feel the burn and that's what's important. Antoncic has just started an Indiegogo campaign to help fund his design and is seeking $80,000.
