STEP 1: Find your size
To determine the correct Ottobock size:
- Measure the circumference of your residual limb at 4 cm up from the bottom end.
- Choose the Ottobock size, which corresponds to your measurement or is immediately below the indicated measurement.
Never choose a liner size that exceeds your measurement. Example: If the residual limb measures 23.5 cm at the indicated location, choose Caleo size 20 not size 25. Selecting the correct size is very important.
If you're in-between sizes, we suggest remeasuring again to be on 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. Continue to STEP 2: Length
STEP 2: Length
Length is a matter of preference. You can trim this liner with a very sharp scissors. Start by applying your Ottobock Liner and mark on the liner where you want to trim. Remove your liner and trim at your mark.
