Size Chart - BK - Willowwood Alpha Hybrid Liner

STEP 1: Bottom Circumference

Measure the circumference of your limb 4cm and 30cm up from the bottom. Continue to STEP 2: Find your size 

 

Measuring for Willowwood Alpha Classic BK prosthetic liner.

STEP 2: Find your size

Take your top and bottom measurements 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 or you can contact our team and provide the serial number printed on the side. Continue to STEP 3: Length
