ALPS South

What ALPS South does

ALPS South, LLC is a privately held US medical device manufacturer founded in 1988 and headquartered in Saint Petersburg, Florida, specializing in lower-limb prosthetic solutions. The company designs and manufactures a comprehensive portfolio of prosthetic liners (gel, silicone, and fabric-based), suspension sleeves, prosthetic feet (the BioStep line featuring NRG Technology), the ProStride knee, the VIP elevated vacuum suspension system, and supporting accessories including volume management socks, residual limb care products, and locking mechanisms. Its proprietary technology stack includes the OptiGel formulation, micro-cratered silicone surface modification (which reduces static friction by 80% without chemical additives), fabric covering technology, and reinforced distal end construction, all supported by a portfolio of registered trademarks and patents.

The company operates a sales-led go-to-market model targeting certified prosthetists and orthotists (O&P professionals) and prosthetic clinics through direct sales representatives. ALPS provides free casting kits to facilitate product trials and publishes clinical studies (gait analysis, VIP vs. pin-lock comparisons) to substantiate product performance claims. Distribution is supported by strategically placed offices in China, Europe, Italy, and Ukraine, enabling global reach while manufacturing remains US-based. Revenue is generated entirely through hardware sales across the product portfolio, with no disclosed pricing model or contract terms; volume management relies on direct professional relationships rather than third-party resellers in core markets.

The end customers are lower-limb amputees (transtibial and transfemoral) who require prosthetic components for daily mobility, with the company also serving the clinicians and healthcare institutions that prescribe and fit these devices. ALPS has earned industry recognition including the 2025 Best in Show award at the AOPA National Assembly for its UltraSeal Gel Liner, and maintains a philanthropic partnership with ROMP (Range of Motion Project) to extend prosthetic access to underserved populations. The company is privately held with no disclosed external investment or parent organization.
