They look cute but offer no support whatsoever. They come off really easily too. I wanted a pair of winter slippers for my just-about-to-start-walking son but unfortunately these are only ok to wear when using the pram.
This book is great as it explains everything you need to know about Hashimoto's. It is quite well written (better that Haskell's book) and easy to understand. It has many suggestions about steps you can take to improve your health as most doctors seem to think that the only way to treat Hashi's is with thyroid medicine. However, i think it is of greater help for those living in the US as many supplements that are mentioned are simply non existant in Europe... Izabella has a great website full of info and it is really worth following her on FB.
