i couldn't be happier with these-although i must admit that i was skeptical in the beginning due to the price. but in the end i am a happy camper with the quality and the fit! i bought a 12-18mth size for my now 10mth old who is 22lbs/76cm. they are great for his creeping sprints across tile floor as well as evening strolls out on breezy days. love 'em
