The ErgoDynamic forearm crutches are available in (3) spring rate size options:
(SMALL) up to 154lbs (70kg)
(MEDIUM) 132 – 198lbs (60-90kg)
(LARGE) over 176lbs (80kg)
If you are within 10lbs of the high end of the suggested weight range, we suggest you select the next higher spring rate/weight option. If you are only using a single crutch as a cane replacement then we recommend going down to the next size.
Example. If you are using both crutches to support yourself and you weigh 188lbs, we suggest you select the LARGE version. If you are using a single crutch only and you weight 188 lbs, we suggest you select the MEDIUM version.
