CustomFit Xtreme – Maximum clinical protection and value

September 3, 2026 by

With the launch of CustomFit Xtreme, we are introducing the most technically advanced prosthetic cover to date. This new solution represents a deliberate expansion into highly demanding technical territory. It positions the cover as a maximum-protection system within a modern prosthetic fitting concept, while still maintaining a sleek, anatomical design. Engineered for maximum compatibility, it is a fully custom-made solution for both transtibial (TT) and transfemoral (TF) patients, integrating seamlessly with the vast majority of prosthetic components available on the market to deliver clear clinical and operational advantages for both prosthetists and their patients.

Component protection & economic value

The CustomFit Xtreme is specifically engineered to take on the impacts of daily use so the prosthetic components do not have to. Its interior features built-in structural defenses designed to shield high-value prosthetic components, ensuring that sensitive parts such as knee joints, expensive components, adapters and electronics remain fully secure. By redirecting physical stress away from the prosthesis, the cover acts as a crucial safeguard for the patient’s setup. This provides significant economic value by preserving the integrity and extending the lifespan of what is ultimately a major clinical investment.

Target patient profiles & clinical value

While the CustomFit Xtreme is perfectly suited for highly active individuals, specifically those with K3 and K4 physical activities levels, its exceptional protection capabilities go far beyond  this group. This cover also provides essential safety and a strong clinical argument for specific patient profiles:


  • Users with an increased risk of falling or elderly and less stable amputees.
  • Patients exposed to frequent impacts due to their profession or outdoor activities.
  • Workers’ compensation or health insurance cases where medical, functional and economic benefits are essential.


Engineered durability & design

Unlike conventional covers, the CustomFit Xtreme features an advanced deep-dyed finish (available exclusively in black). Instead of just being painted on the surface, the color is integrated through the entire material, which delivers improved resistance against scratches and daily wear without ever showing signs of deterioration. Enhancing this structural durability is its single-piece design. The cover wraps around the prosthesis as a seamless engineered shell secured by powerful integrated magnets, ensuring there are no gaps and no additional weak points in the system.

Seamless clinic integration & value

Incorporating the CustomFit Xtreme adds no additional complexity for prosthetists, as it relies entirely on the same familiar workflow. The ordering procedure remains completely unchanged, utilizing the standard scan or photo-based process that clinics already use through the UNYQ App. It allows clinics to offer advanced protection features and maximum durability to their patients at the same price point as the CustomFit Flex model.

Ready to explore CustomFit Xtreme?

While our Flex line focuses on an excellent balance of protection, design & personalization, the new CustomFit Xtreme is built for those who require an entirely different level of defense. It offers significantly greater impact resistance than any other cover in our catalog, prioritizing maximum technical protection and structural durability above all else.
