Sustainability leader Dalbellos Reboot project has set the trend by launching one of the most sustainable ski boots. The Green Gaia 3.0 GW is a high-performance girls three-buckle boot whose shell and liner are made almost entirely out of recycled materials. The entire boot is also recyclable. The Green Gaia 3.0 GW is really easy to get on and off and was developed for maximum fun on the slopes. Pre-fitted GripWalk soles have lots of grip and make walking much easier.
