I purchased this on Rakuten. I only tried it once in the shoes I intended to use it with, but I haven't actually used it. It was thicker than I expected, and it looked like my feet wouldn't fit, so I gave up on using it and am now selling it. It might be suitable for shoes with extra room around the foot, such as rain boots or boots. It's fluffy and warm. Please understand that this is a used item. ☆
