I will start by saying I opened the box and thought, Wow, these are chunky for sure! I held them in my hands and thought, wow ok not nearly as heavy as I thought. I thought they felt like great material holding them in my hands, and I loved the material. Not too thin and not too thick. Just enough to make them breathable and not feel heavy. I am a size 9, and they fit me perfectly. Yes, Nike runs small, but a 9 1/2 would be too big for me, so I say get your normal size. I have had many pairs of Nike and always skipped Air Max because they seemed so heavy, but I am always reading reviews, and I was finally convinced I had to try them. So happy I did!! These shoes are so light and feel amazing on my feet. So many times I put on sneakers, and they hurt my toe, but not these! Not even the first time I wore them. It was like they were broken in already. The design is great, and I have no idea why it took me this long to appreciate Air Max. They run true to size and fit snug (in a good way), that is how I want them to fit. Feels like part of your foot, literally. They are so comfortable, and I highly recommend them. I have nothing negative to say about them. I am buying another pair, but in pink this time!
