About the Crocs Hydra Boot 'Galactic Grey'
The Crocs Hydra Boot 'Galactic Grey' presents a neutral monochrome colorway of the towering silhouette. Built with water-resistant Croslite foam in a medium grey finish, the upper features a knee-high shaft with a sculpted back handle. Exterior branding is limited to a Crocs logo debossed on the heel. The boot is mounted on an elevated platform midsole, supported by a lugged outsole that offers grippy traction underfoot.
