Bought these for my Zumba class and they are defnitely lighter than my regular running shoes. I have a small foot  5 1/2 so I ordered a 6 thinking the 5 would be too small. My running shoes are a 6 but are heavily padded inside but these shoes don't have as much padding inside and are mostly of a breathable mesh material on the top that stretches some so I was concerned about the fit. When I tried them on they did fit but I had to really tighten the shoe string for a snuggger fit. After walking around the house with them and trying some lateral moves I felt like my foot was sliding inside, especially with side moves so I decided to take the advice of another reviewer and added Dr. Scholls shoe inserts under the original ones and then they fit good and made them more cushiony for extra foot support. Unfortunately they don't have half sized in this brand which would have been great for me but as I mentioned I solve the issue with the extra padding. I think maybe people with half size shoes will run into this problem. The shoes seems to be true to size and the multicolor look of them will make it easy to coordinate with gym outfits .They are definitely very attractive shoes and they come with 5 extra shoe laces that match the colors that you see on the shoe.. I tried them at my Zumba class and they are comfortable and my foot stayed cool, dry and didn't slide around anymore. I would recommend them but if you wear a half size shoe and or have a slim foot beware. A tip if you want the shoes for cheaper just sign up for Amazon shoe alert e-mails and you will get 20 percent off the shoes. I got them for 60 dollars and free shipping.
