Back in the early 1980s I bought five pairs of Guccis directly from the store. I still have them and they are the most comfortable shoes I have ever had. I decided I want to get more pairs if the price is right. I have mostly been looking on eBay. The Guccis I have are 38 and 38.5 and they fit. I also have a pair that is a 37.5, so I can go that low. I just missed getting a pair on eBay that was a 7.5 and am now watching a pair of 8.5. Since 38 and 38.5 fit, does that mean I am an 8 or an 8.5 in Gucci? In other brands, it doesn’t always correspond that a 38 is an 8, a 39 is a 9, etc. So, will an 8.5 be too big if I wear a 38.5 in Gucci? Or will it be just right?
