You can usually eliminate this by folding the footwear onto itself, that is skin against skin, and gently rubbing it together. Sheepskin is quite resistant to getting totally wet. You can get caught in a shower with your sheepskin boots, and on the outside they will appear considerably wet but on the inside you are warm and cosy. This is because not only does the rain have to soak through quite thick skin, but also penetrate the 5mm plus wool on the inside. Sheepskin is one of those unusual materials of which there is no equivalent.
Most people know that leather shoes stretch.
Well with sheepskin shoes, this happens even more so. This is because they stretch. Another key factor is that wool compresses with your weight. You might start with 5mm plus wool poking at your toes from all angles but soon you will find the wool flattening leaving more room. With some styles, such as the Hi Boots, the toe area will dome up at the front, moulding to the shape of your feet.
