Aqualeg's hybrid semi-soft cover fits precisely to the socket and is self supporting. Foam is no more necessary. This cover has a flexibility close to real limbs. It's available in standard (from patient's calf and ankle measurements) to precise 3D custom fabrication shape. Every cover is precisely created to fit each patient's socket. "Hybrid" by nature, it's the essential key for water activities as well as for everyday use. Functional and protective, it's the solution for prostheses usually hard to cover, especially those using electronic components or vacuum assistance systems
