I ended up ordering SIDI's new winter shoes. Its showed up and I was unimpressed with the shoe altogether. So I sent them back and ordered the Northwave winter shoes. The fahrenheit GTX, its the new one. I've had them out twice now and am not overly impressed with the insulation. After about 45 minutes my toes were cold. The temperatures were in the mid 30's. I'm not sure what to try next, maybe to heated insoles. Hope this helps!
