After a disconnect they will flash blue red, power button does not turn them off either by holding multi clicking or clicking once. Seems to be well made but the straps for the foot and toe were to far back (maybe good fit if you have long toes?) so it didn’t work for us and had to return. exactly as advertised & I am very happy with them! I never complain and I don’t like to but I did want to let other people know to maybe not cut off the label before trying. I just truly believe if they added those 2 things the product would be a 5 star wonder! Meaning Im often upside down during training. These shoes are comfy and versatile. The only problem I see is the fabric is starting to fade after only a few wears. I’m 5’8 135lbs and ordered a Medium! However, they are very, very thick.
