I have the foot Active Sport ordered on Wednesday night and received on Thursday afternoon. Superfast. I then worn for one day and found that the little much for me, but (I had 3 weeks ago a Knieop, the doctor gave me prescribed heel inserts but the slip and bring nothing) I wanted this time to do everything right with my knee and got the customer called and described my problem. There followed a competent advice (the soles with the largest increase were simply too much for the Knieop) I can keep the soles and get free a couple of the better fit for me. I would get my money back but I prefer to the soles, because the feeling in the soles was great. Good maintenance. Butterweich. We recommend. Update: these soles make the cheapest most uncomfortable shoes to a shoe you do not want to take off. You walk on clouds. I look forward every day on the soles.
