Laid down my ultra a few days ago.  My foot/shoe was caught under the bike from about 50mph till 0 MPG under a smoking hot exhaust pipe and with fuel from the just filled up tank pouring all over it.  My foot came out unharmed and even the weight of the bike was managed from the toughness of the shoe.  They had started to show signs of wear where the show bends and the rubber meets but these things are like steel for shoes.  I highly recommend them if you want something tough but in a shoe.  Plan to buy a new pair about every year if you ride a lot as the tread will wear down and the bottom will loosen from the rest of the show.  Solid and feels like a tank on your feet.  Good buy. I bought a 10 and usually wear a 9 1/2, wished I had bought 9 instead.  They ran large for me and my foot wanted to slip too much.
