The Powerslide Swell Marawa 100 Skates were made collaborating with Marawa and they look and feel like a dream! They are built and ready for intense fitness skating and cross-training activity. Inside are very comfortable built-in MyFit liners which are made with recall memory fit foam. They have standard lacing, a velcro 45-degree strap, cuff buckles, and adjustable cuffs that allow you to raise/lower to customize support and flex a bit. Underneath they have holes for ventilation which is great for long rides and keeping your feet cool and dry. On the outside, the boots are made with a hand-lasted hybrid composite with TPU materials being used to make it abrasion-resistant. The boots use Trinity Frame Mounting which is amazing for energy transfer as it connects at 3 points of the boot right where your foot's pressure points are. The winged mounting and 3D casted aluminum frames position you lower to the ground, giving a great amount of stability and energy efficiency over 100mm 85A wheels made with a very cool glittery transparent PU.
