SKATE-TEC LT 4G 17 boots

4G 17 Long Track Speed Skating Boots

The Groothuis 4G 17 is a premium semi-custom long track speed skating boot developed by the renowned Dutch boot maker Groothuis Orthopedische Schoentechniek. Built using the same manufacturing methods as the company’s custom-made boots, the 4G 17 delivers exceptional performance, comfort, and fit in a standard production model.

Designed around an anatomically shaped last, the 4G 17 offers a precise, race-oriented fit while eliminating the cost and waiting time associated with fully custom footwear. It is an ideal choice for competitive skaters seeking professional-level performance without the expense of a bespoke boot.

The lightweight carbon-fiberglass shell provides excellent torsional stiffness for efficient power transfer while maintaining just enough controlled flex to deliver outstanding edge feel and precise steering through every push. Its fully thermoplastic construction allows the boot to be heat molded multiple times, creating a customized fit that closely matches the skater’s foot anatomy.

Inside, a durable microfiber liner surrounds the foot with a comfortable, moisture-resistant interior that maintains its shape over years of training. The synthetic leather outer finish offers durability and a clean racing appearance while requiring minimal maintenance.
