A gift for my son,he was very haooy with it. This was not the best technique (should have done length wise, as it left me with only one side containing the pull tab that is used to later remove the strip. Beautiful Shoes! Absolutely what I expected and more. Arrived charged up and ready to go- nice surprise. So not all Birkenstock styles have the same footbed (I think Birkenstock has 3 different footbeds). Very good connector to my iPad Pro tablet. The stem end of the feather was poking out and sharp if you touched it! All i wear is MK these arw the real deal for a great price. Comparing with my current headphone, Sennheiser true wireless, the battery life is much better.
