However they are heavy, and for our adventure cruise in Hawaii, I decided to try the Keen Clearwater CNX sandal instead. sich nähernde Autos oder Fahrradklingeln anderer Radfahrer zu erkennen, wird dieser Modus nicht gerecht. These are great, but not a permanent solution. (Other reviews were correct: these do run a tiny bit small. I dont recommend this unit. Unfortunately this is not the case. The only issue I have with the device is the cost of the salt pods. Ce nétait pas indiqué. I think it still be good for bike riding though. Also, the smell!
