Please see attached image of ladies easy velour stab stitch grosgrain lip back mule slipper which I am going to introduce.The upper material is easy velour,some of countries call it to be EF-velour which one kind soft material which was spread used on to toys and recently it used on to thermal underwear and from this you will know how warm it is.The lining/sock is easy velour either as it has good perspiration resistance and air permeability.The outsole used synthetic suede which is one kind of good material to ba as outsole to protect your flool board and carpet and it also can pass slip resistance.Synthetic suede has another advantage is light.
