The perfect cold snowy weather boots! I love the solid black and they are sold out online! Great preowned condition with no flaws, just a little dirt/wear on the toes. Size: 7 Stylish and functional winter boots for women from Sorel. Joan of Arctic Premium is a slightly more luxurious version of the classic Joan of Arctic boot. It has essentially the same construction, with a natural rubber foot, a waterproof shaft and internally sealed joints. The big difference between the original and the Premium boot is that the Joan of Arctic Premium has a shaft in fully tanned smooth leather. The foot is made of natural rubber, and this has several advantages. Firstly, natural rubber weighs much less than artificially produced rubber, and secondly, natural rubber remains soft, even in severe frosts. The soft rubber, together with a herringbone patterned sole, ensures that the boot stands firmly on wet and slippery surfaces. Inside the Joan of Arctic Premium there is a 6 mm. Thick felt sock that keeps the feet pleasantly warm. Sorel has tested the Joan of Arctic Premium down to -32 degrees. Joan of Arctic Premium is the perfect winter boot for those who want a functional boot that is modern without being too eye-catching. The entire boot is kept in black, all the way from the sole to the beautiful faux fur snow guard at the top. The only thing that stands out a little is the rings that hold the laces and the button details on the side, which are metallic.
