I am about to order a replacement pair of these boots.  I got my first pair in 1995 (it's now 2012) and they are still in pretty good condition, except for wear on the outside of the heel, which is a problem with my feet and not with the boots.  I don't know if I'll be able to throw the old pair away.  I have about 5 pairs of Doc boots, plus about 5 pairs of shoes, and I agree with comments that they are hard to wear in (a lot of sports tape required) but it's worth the effort and the short-term pain.  I take a size 10 in Australia and I get UK size 8 boots/shoes.  They are a little bit big (I'd prefer a 7.5 but that's only available with the 8-hole boots) but with some thick socks all is good.  The boots here on Amazon today are really cheap ($98) compared with prices in stores here ($260-$300).  I think everyone should have a pair!
