Why would you use anything else?
First off,  no one should have to use those under arm crutches.  This is the only way to go.  I'm 5'1 and honestly  I do not know if I should have gone with the size up or not.  These fit, but I wondered what one more notch higher would have been like. I'm right at the cut off.  Adult underarm crutches (gd awful) which were for 5'2 and taller  were just too big.  They're lightweight.  Adjustable. The forearm grips are aluminum and I squeezed them together to get a better fit.  I would recommend them to friends or family who need crutches.  And for the cost, plus a day shipping, it beats the cost of the pharmacy markup.  Oh, as a gag,  I bought several rolls of colorful duct tape and personalized my crutches and boot/cast to match.
