Measuring for Alps Smart Seal prosthetic liner.

STEP 2: Find your size

Take your bottom measurement and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on the safe side. If the size you arrived at, after measuring seems too big or small, in some cases it helps to use the size of your current liner as a very rough guide. The size may be printed on the liner. Continue to STEP 3: Length

SIZE CIRCUMFERENCE (centimeters)
20 20-23 cm
24 24-25 cm
26 26-27 cm
28 28-31 cm

STEP 3: Length

Length is a matter of preference. You can trim this liner with a very sharp scissors. Start by applying your below-knee Alps Smart Seal Liner and mark on the liner where you want to trim. Remove your liner and trim at your mark.

 

When measuring your thigh, pay special attention to how tight you take your measurement. It's best to pull the ends of your tape measure somewhat tight and then release. Your goal is to find a middle ground of how much tension you should apply to your measuring tape. Too tight and too loose will both result in a poorly fitting prosthetic liner.

Alps Smart Seal Liner Description

The Alps Smart Seal Liner for below knee prosthetic users is a sealing-type liner designed to offer enhanced suspension compared to standard cushion and locking prosthetic liners. With its formulation using Alps HD Gel, this liner provides below-knee amputees greater stability and control over traditional gel-type liners, making it an excellent choice for those who engage in sports or frequent the gym.

Benefits

  • Non-constrictive hypobaric (less pressure) suspension
  • Below-Knee sizing available
  • Alps' HD Gel ensures ideal combination of comfort and stability
  • Silicone coated sealing bands that create suspension and prevent slippage
  • Engineered for those prosthetic users transitioning away from silicone prosthetic liners.
  • Available in 3mm and 6mm uniform thicknesses
  • Premium seamless knit outer covering limits excessive stretch and pistoning
  • Latex free and hypoallergenic
  • Cushion Liner, not made in locking version
  • Black and brown color combination
  • Locking pin is not included
  • Made in USA
  • Sold individually in a polybag

Suggested Use

The hypobaric and non-constricting design minimizes pressure and stress on the residual limb, promoting additional comfort. Silicone-coated bands provide rotational control, while below-knee amputees can enjoy a secure cushion suspension without the need for a prosthetic sleeve. The silicone bands of the Alps Smart Seal Liner stretch against the walls of the prosthesis, preventing slippage and maintaining stability.

The premium knit fabric used in the Alps Smart Seal Liner limits vertical stretch, ensuring a more secure fit. Its seamless knitted outer fabric not only adds a modern look but also extends the lifespan of the HD Gel. Available only as a cushion liner option, and in two uniform thicknesses, the Alps Smart Seal Prosthetic Liner is ideal for those replacing their current liner with a 6mm or 3mm uniform thickness.

How-to Apply

Prior to applying your Smart Seal Liner make sure your residual limb is clean, dry, and free of any soap residue. Cover any open wounds and non-intact skin with a product similar to Spenco. Alps states to avoid using any type of animal based lotions or powders on your residual limb or liner. These products may damage your Alps Liner.

Invert your Alps prosthetic liner so that the logo is on the inside. Place the end of your liner against the end of your limb. If using a pin lock liner, center the pin attachment on the bottom of your limb. Carefully roll your prosthetic liner onto your limb.

***Warning: Do not pull your liner onto your limb. Pulling the liner may stretch the skin and result in an uncomfortable fit and possible skin issues along the edge of your liner. Last, make sure that there are no wrinkles or air pockets between the liner and your limb. Air pockets cause excessive sweating.
