I have this pair of shoes, in a size 9.5 in fact, purchased from Bluefly. I had initially purchased the shoes in a size 10 (my usual size), but they were way too big, so I returned them. I am experiencing slight heel slippage even in the size 9.5s. Should the fit improve after wearing the shoes several times, or are the shoes too big?
Your experience is similar to my own, although a bit more extreme. I also had heel slippage when I first wore those shoes. I don't know why it is, but the 89 last just seems to be significantly roomier than the other EG lasts that I've tried. The shoe was wider than any other EG D width shoe that I've worn, and there was the heel slippage. Partly because the slippage didn't bother me too much and partly because I wanted to keep the shoes very very badly (you young people should do as I say, not as I do.
), I kept the shoes and wore them. The slippage has since pretty much gone away. Still, you've worn your shoes, not me, and I would be hard-pressed to recommend that you keep shoes that don't fit like you want them to in the hopes that the fit will improve with wearing.
