Query: Exceptional quality and comfort!

These shoes are amazing. The sole is thick enough to get through snow and sleet that tends to accumolate in cities without weighing the shoes down at all. They are FAR lighter than they appear. As for comfort I have been able to wear them for 16 hours straight without any issues, they might not be as comfortable as a broken in pair of sneakers, but they come darn close.
