I use this shoe for my triathlons that I do. I like the quick tightening and loosening feature of the Boa. I prefer this shoe over triathlon specific shoes because it is stiffer. The only very slight drawback that I have encountered is putting on rain, cold weather and aero booties. My booties fit quite tight and tend to pull up and release the Boa system when I'm putting the booties on and off.
