How to get measurements for the Dry Pro
1) Measure Opening
Arm: Measure the circumference of the arm just above the cast or bandage (If the end of the cast is very close to the elbow, measure mid bicep.)
DO NOT MEASURE AROUND THE CAST, MEASURE AROUND THE SKIN
Leg: Measure the circumference of the leg just above the cast or bandage (If the end of the cast is very close to the knee, measure mid thigh.)
Arm: Measure from the tip of the middle finger to the top end of the cast or prosthetic. If the cast goes above the elbow, follow the bend of the arm.
Leg: Measure from the back of the heel from the floor (or toe if heel is bent past 90 degrees) to the top end of the cast or prosthetic.
Don't worry if the Dry Pro waterproof cast cover is too long. The excess material of the cast sock will flatten down when the air is pumped out.
