I've been wearing converse slip ons for at least ten years and buy a new pair every year or so. Last year, on ordering my newest pair, I was shocked to find they didn't fit! Converse seems to have changed their sizing to make the shoes much narrower and more stiff. Why they would do this after years of selling the same product is beyond me but I was able to find an older gray pair with the previous sizing to get me through the year. This year, I went for this gray again and they fit just fine. Looking at the Converse site, it doesn't look like they are making the slips anymore unless they are custom, so I'm seriously considering order a few more pairs while they are available. So sad that manufacturers do this kind of thing, but I'm glad amazon still has these!
