Fun fact: even “regular style” crutches are not actually supposed to rest in your armpits! You are supposed to hold onto the arm portion and use them similarly to the above crutches. When we adjusted that for the spouse, we had to shorten the crutches by like 2-3 inches and he said it was WAY more comfortable.

There are some videos on YouTube by physiotherapists etc that were supremely helpful - recommend giving them a quick watch and readjusting your crutches.
