I have a medium roof box and it fits with some roof to spare but not a lot. My second pair in about 16 years. They connected quickly and easily to my iPhone! The only reason I gave 4 and not 5 stars its because I ordered 8 and they feel like 8. Great vacation sandals. Been waiting for one that really delivers at a reasonable price. Falls es einen Nachfolger geben wird hat dieser Potential die beste Maus zu werden. Which is a massive disappointment because the product itself is phenomenal. My feet were comfortable the entire day. Already have had tons of compliments on them!
