Comfort plus and totally ventilated. Insert one long screw into the ?roof? and secure. No blisters and no pain is a plus ! I love that the kids shoes are half the price. The ridge of the sewn strip just hits the bottom of the foot causing the stitching to rub in an irritating manner. If you need a charging cable for your kids right now to keep them entertained these are great! After receiving this hose I noticed it was very stiff, but it was like an accordion and could be pulled and pushed to greater or lesser lengths. Works great, was missing lid of original box but other then that they work great and the package smelled good idk why. El producto no funciona bien, el manual es pésimo, no se puede contestar desde el producto, si se desconfigura y se intenta reconfigurar no se puede hacer siguiendo las instrucciones Because of my history of wearing Aerosoles, I was completely confident about buying shoes online instead of trying them on.
