I tried this shoe in a store prior to purchasing it on amazon - so I pretty much knew what to expect when I opened the box. But the attachments are what screwed this product over. Poor quality construction and cheap materials. This pair are comfortable and easy to walk in when off the bike. Attenti a non lasciare montate sul portabici le gomme che toccano i tubolari, senza la bici tendono a scivolare via, infatti io ne ho perso uno. It was extremely easy. And yes I played with all mic settings. Even my son was impressed by the look of the shoe, and you know how young folk are about their shoes! So, it?s a ?one size fits all? earbud. That can be a good thing or a bad thing depending on you.
