These inserts are great and I wanted to order them years ago; I wish I had sooner.
They are very fluffy which made my non-Ugg (Timberland) boots tight at first. After a day or so of wear they conformed to my feet and felt normal. They add warmth to my boots which is great for winter. I only wish I had ordered even larger than my size so that I could have added more cushion to the back of my ankle--like how Uggs are designed inside.
I bought these insoles to go inside my Hunter rain boots for use on a trip up East. They fit perfect, and keep my feet warm. They also fit perfect to replace the insoles in my UGG slippers. I'm going to buy another pair.
My slippers were getting a little used, but only the insides. These saved my slippers!!! Now I can keep them for many more years. Super easy to put I slipper and perfect fit. So happy I found this.
