I bought a pair of Norfin Yukons off of http://www.anglingproshop.com a couple of years ago. They’re comparable to the Norfin Klondaiks (sold by Thorne Bros.), but they don’t have a built in spike. These boots are extremely light (each boot weighs just over a pound) and extremely warm (down to -58 degrees Fahrenheit). I highly recommend getting a pair!
