NEW REVIEW:I ordered a half size up and they arrived today. They are PERFECT!!! I WAS going to go to the Adidas Employee Store tomorrow but not anymore!!!!!!! I actually had purchased a pair of Nikes but they arrived and were SO uncomfortable I immediately returned them. I decided to just try a new pair of Adidas but then I went ahead and got these and they are like walking/running on clouds! Get them! You will not regret it!PREVIOUS REVIEW: I already own a pair of these and LOVE them so I bought a new pair as my old pair is getting worn out. However the new pair doesn't fit me. It's too small. I returned them and I am buying the next size up. I am not sure why the new pair was smaller but I think going a half size up will solve it. I am usually a 6 1/2 but my old pair is a size 6 so I ordered a size 6. But they were just too tight and not comfortable. I will order a size 6 1/2 and hopefully this will solve the problem. I see they are manufactured in China so maybe the quality standards were off or something? But bottom line: the boost shoes have AMAZING cushioning and as an aging runner, I need ALL the help I can get!
