My wife also wears wellies very often and she loves them. Here is a picture of latest purchase, Hunter refined tall riding boots. As clearly visible, these boots are much taller than original model. Boots are up to her knees really, but sitll comfortable to wear becouse of soft material and U -shaped cut at backside. These Hunters are great for wellie filling fun, they are so tall that the mess inside won't spill out too easily. So we had to test boots for wellie filling, the very first time she pulled her new tall Hunters on she first poured porridge inside each boot. It was a great feeling for both of us.
