skan wrote a review of The North Face NSE Traction Mule - Men's on December 12, 2010
Warm, but not as much as expected.
It has a bulky and very uncomfortable plastic seam in front of the toes.
It's warm but it isn't worth its price.
It has a cold spot all along the joint of the sole and the upper.
They claim to have "supreme traction". Maybe is good on earth but not on tile.
It's very expensive.
