STEP 1: Top & Bottom

Measure the circumference around the middle of your knee cap and 2 inches up from the bottom of your residual limb.  The bottom circumference is the most difficult to measure because it may feel as if the tape measure is sliding off your limb. Continue to STEP 2: Length

STEP 2: Length

Length is a matter of preference. However, the typical rule is 2-3 inches past the middle of your knee cap. Continue to STEP 3: Find your size

 

STEP 3: Find your size

Take both your top, bottom, and length measurements and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on safe side. Most below-knee amputees fit a size "Regular."

STEP 2: Length

Length is a matter of preference. Many people prefer their prosthetic sheath to end 1-2 inches before the top of their socket, while others prefer the sheath to stay within their socket, well below the top of the socket. Continue to STEP 3: Find your size

When taking body measurements, you need to use the correct type of tape measure. You will want to use a soft cloth or flexible plastic  tape measure, similar to what a seamstress uses. Do not use a metal measuring tape, used in construction (your measurements will be inaccurate).  Please don't guess, if you still have your sock packaging you can refer to the packaging size tab.  Pay special attention not to pull your measuring tape too tight.  Doing so will produce a measurement that is too small. 

The most difficult measurement is the bottom measurement.  Too often, people measure too high along the bottom of their limbs producing a larger "Bottom" measurement.  Ideally, measure 2 inches up from the bottom of your limb and use a pen to mark this level on your limb. Once you know exactly where to measure, use a tape measure to carefully measure your bottom circumference.

Knit-Rite Prosthetic Sheath Description

Knit-Rite Prosthetic Sheaths are engineered to primarily reduce friction and act as a moisture barrier. Prosthetic sheaths when combined with prosthetic socks are the ideal team to combat friction. Whether you are hiking or carrying on with your day, your limb’s volume is going to fluctuate. And when volume goes up or down is when friction is at its worst. Apply a Knit-Rite Prosthetic Sheath before you add prosthetic socks will help manage friction during “limb volume fluctuation”. Knit-Rite Sheaths have transfers (Knit-Rite's logo) on both sheaths of the pair to help you position the prosthetic sheath to maximize comfort.
