Better than nothing I guess? How disappointing to try on the Portsmouth II shoe and discover the fit wasnt right and the shoe was incredibly uncomfortable--particular the back of the shoe by my ankle. 4) turning on and off manually takes significantly few seconds longer on these buds than the pros. The strap in the back is a lifesaver, as she needs it for the shoe to stay on and in place. Hard to believe this sound for the money. I like them nice fitting slide, and can be worn with nice outfit. I have worn Birkenstock sandals for about 20 years now, usually getting a new pair every couple of years. But we finally got it done after about 2 hours (with two people working on it). Also for those that complain about instructions in Chinese? Please get with this century and use Google Lens. The first one was good, and lasted five years; the second one was serviceable, and lasted two years; this one is a disgrace.
