These shoes have a slightly weird design but are overall pretty comfortable. The tongue is one piece with the shoe  so it does not have as much flexibility when taking them on and off as a normal shoe would. I normally wear a size 8 in other sneakers and these size 8s fit perfectly. They are bright and vibrant as Zumba shoes should be and there is plenty of cushioning and support. The olive greenish plastic on the outside is my least favorite thing. Not sure why they would use that color with a neon green shoe instead of the black they use with their red shoes.
