looking for a pair of shoes/boots that are VERY comfortable for standing and walking long periods of time but warm enough for the fall/winter. I've had a great pair of sandals by Prive for Clarks but i wont be able to wear them much longer. Comfort trumps style here but I'm hoping to get some combination of both. Willing to spend up to about $150 but hoping to keep it under $100 if that's possible.
