I put 400 lb on the J cups, there was no issue. These fit perfectly and are warm and seem to wear better than womans shoes. Its been almost 5 months since I got these shoes and theyre barely wearable because the backs have legitimately broken down and deteriorated. This should definitely be your first pair of wireless headphones. We love the way the bottom hoop holds up the train of my daughters wedding dress. The case is still going ands protecting my airpods. Kinda uglier in person vs the photos. I am going to wait and see how they wear. After thinking about this, three stars might be a little generous. I am not about that 50 mile a day bike ride life.
