NB all terrain shoes. 1st time I wore them on concrete.
Some suspicion that all was not right, but I put it down to the short nubs on the sole. 2nd time I wore them: On a varnished wood floor, no wax, and never a problem on that same floor with any other shoes, boots, or sandals I've worn in the past 12 years. The NB sole is so slick that it was like walking on a hockey rink in leather soles right after the Zamboni made a pass. No warning at all of how slick they are.
A booby-trap for the unwary. Unsafe at any speed.
Product or Service Mentioned: New Balance Shoes.
