I bought these Mizunos for a specific purpose which is to play dance dance revolution/in the groove another dancing game. They work very well when playing but I am having a single issue no matter where I go or even when I am playing. When I am walking on a NON POURUS surface something such as linoleum or plastic or very smooth hard rock say Marble or a smooth wood floor that has been stained, there is an issue with the heel of the shoe getting stuck to the ground like a suction cup. It legitimately sucks to the ground and gets stuck on every step. it has to be one of the most annoying things I have ever come across with a shoe and ever experienced. The only way I got around this was by taking a razor blade and literally cutting up the heel of the shoe so it did not have an area to create suction.
