Yes. Make sure you use our crutch sizing chart here – Selecting your Smartcrutch Size
We recommend that you choose the cuff size (small, medium or large) with an extended lower leg which will allow for height range from 6’4″ to 6’7″. So the extended leg would be for you! You just select your correct cuff size with the extended leg in the order drop down and you will be sent a pair with the longer legs automatically.
