Its study and I enjoy using it. So far my toddler can walk in them without problems. They wouldn?t have been dressy enough as an all-day guest or in a different outfit (I erred on the smart-casual side rather than wedding formal) but were perfect for my purposes. Cant read them even with a magnifying glass. The extended sole sticking out the back of the shoe is a visual disaster. La facilité de connexion, sans souci et facile. The instructions were pretty easy to follow. I took it off, remounted it, and it still moves while riding on the trail. The battery life is good and the sound quality is great. In my opinion, it?s not worthy this price.
