These types of shoes do not have any arch support, so be cautious as to how long you wear them daily. One Figure 8 session per day would be fine, but we do not recommend wearing them all day. If you have any foot issues, it is recommended to wear shoes that have good arch support like cross-training shoes. Ones that will allow you to move laterally is best.
