I love love croc sandals. I dont think we are being particularly careful or delicate with the Trail Chaser shoes. There is no support at all. this one has very large thick rubber suction cups between the magnets and roof making it with added strength on attachment as well as added protection to any paint damage from what magnet mounts can do to vehicles. So you mount, not on sheet rock only, but through the sheet rock and into 2x4 studs. Im certainly not a heels or pumps kinda gal. I purchased this speaker as an upgrade to the one we?ve enjoyed for years (by the same company) this model was supposed to have a better battery life etc so we ordered and received it May 2nd 2018. TE INVITO A LEER ESTO ANTES DE REALIZAR TU COMPRA, ESPECIALMENTE SI ERES DE MÉXICO. These are cute and warm, and easy to slip on but stay on your feet. These shoes are a life-saver.
