No doubt you will love these shoes. It is actually a 1700 watt unit during operation My husband always wears Keen sandals, so I felt confident in ordering his usual size 9s. After hunting around and realising I dont want to spend £40+ for a Quadlock case and mount, I found numerous reviews and sites talking about this holder - The Bike Tie X from Bone Collection. I really wanted to like this case, but I am going to have to return it. I bought this based on the great reviews but I didnt even try this on. Peccato che dopo meno di due mesi si siano irrimediabilmente rotte! Microphone [2/5] : The mic is short and stiff, just like what my gf says about me. But these are a NO GO! We just ordered a replacement pair of Birkis in the last six months, which come with the traditional cork footbed.
