Reviews of the Gravity Defyer shoes are generally positive; however, the praise is not unanimous. Does it Really Work notes that even though the shoes are not miracle workers, Gravity Defyer produces quality shoes.
One of the more common complaints for the women's Super Walk athletic shoe is that the shoes are too heavy at over 1 pound. A few reviews praise the shoes for reducing knee pain and subsequently allowing a more active lifestyle. A common complaint of the men's G-Defy Super Walk athletic shoe is the loud squeaking noise it makes. One review notes that even after three weeks the noise has not abated. Even with some negative reviews, these two shoes, along with other Gravity Defyer shoes, receive around four out of five stars from Amazon.com reviews.
