Size Chart Guide

  • Below-Knee

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


How to measure for knit-rite prosthetic soft sock.

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."

Knit-Rite Silver Sheath Description

Knit-Rite Silver Sheath with X-Static offers the same smart engineering as other prosthetic sheaths in Knit-Rite’s family of sheaths. The Silver Sheath goes a step further and fights odor causing bacteria along with managing socket friction. Adding X-Static to their standard Knit-Rite Prosthetic Sheath makes this sheath a favorite among amputees. Assuming you wear it all day long, it’s nice to know that the Silver Sheath keeps odors at bay and helps keep skin temperature consistent. Knit-Rite placed transfers (Knit-Rite's logo) on both sheaths of the pair to help you position the sheath to maximize comfort.
