I love the Keen shoes always. I wear eyeglasses and have no problem wearing the headset with the glasses. And the price is UNBEATABLE! It can also be used for multiple players games as well. Babolat was too wide and the Mizuno and Wilson was so narrow. 5 as I read they run small and I normally wear a 12. The straps held well (I did have to re-tighten a couple times) and it was able to hold a lot of extra luggage. Very nice bike rack, very sturdy when properly mounted (mounted on my Lexus GS 350 and fits nearly perfectly). It was the best headset I have ever owned. But when I wear a medium weight sock, the shoe feels completely different.
