These keens are very comfortable but run a little tighter in the toe box than most keens but they are still great boots. Locking the phone in before use and removal after ride is simple. With the price I thought it was going to be a thin layer of silicon for the case. overall it?s a good product I highly doubt it?ll last much longer. I was unhappy with the ear gel that was included with the headset as it didnt seem to hold the headset in my ear very securely. I could feel slight warmth. They were working great the day before, but this morning, they didnt work anymore. Rapide a recevoir, aucun manuel d?installation. The adjustable strap is definitely a plus.
