I probably will race in them. But they are probably a little heavy and bulky. Compared to my bonts they look like rectangular bricks on the end of my legs. They’re big but the heel adjusts in quite a bit. So the shoes themselves are a good bit longer than I need...but with the adjustability they fit just great. They just don’t seem like they’d be very aero. But since I’m only going to do one Ironman this year, I said they’re great training shoes because that’s pretty much all I’ll be doing with them...
