Was nervous about getting these due to complaints about knuckles hitting the ground, but happy to report that they are perfect! Very sturdy, really like the thick bars and they will easily fit in my backpack (super lightweight). While a bit pricey I have to conclude that they are worth it.
For reference, my hand length is about 7.25" and I have medium/slender fingers. There is a nice gap between my knuckles and the ground. Looks like another review tested these on a rug and they might have sunk in.
