Have probably bought 6 pairs of this size over the years. So far all have been 5 stars. This one is different. Fits in different ways and although the shoes fit the feel is different. I started getting blisters on my heels after wearing them for less than 2 hours. One of the reasons I have always loved these shoes is that I could wear them straight away without breaking in and without blisters. I don't know why THIS couple is different. They seem to "shrink" after long wear (with socks), but it's definitely a different feeling than before.
