After at least 5 shoe purchases and returns, I finally found a keeper. Working with Zack Foley of Competitive has really helped me find this shoe. I ride about 7,000 miles a year and admittedly am particular on my shoes. I wrote a review previously on the Shimano Sphyres and they were very nice and comfortable but after 50-60 miles, the stitching on the interior Boa dial would be rubbing my pinky toe, which i found a couple other people had the same problem. I have ridden Sidi Ergo 4's forever and recently tried the Wire and the Pushes but the toe box just seemed too narrow and the Mega didn't help as it was too loose. I love the comfort of the Giro Empires but the only draw back was i found myself tweaking the lacing frequently and I wanted something as comfortable but with quick and easy adjustment.......Wala: the Garneau Course Air light 2.
I did the maiden voyage yesterday and did 72 miles in them: extremely comfortable but yet extremely stiff on the pedal pull up and felt like i had every bit of the same power as the Sidi's, only much more comfortable. The ventilation is unbelievable on the bottom of the sole and they do come with cool inserts (perforated Holes)
and hot inserts for different seasons. We'll see how warm they are in the winter but they're a keeper for me. I normally take a 42.5 in the Giro's and Sidi's and a US 9 but I tried the recommended 42's according to the Garneau sight and they were just a little tight front to back so i went to the 42.5's and they fit best for thin socks, thick socks, or custom inserts with the toe box perfect. So i would say they run true to size
Forgot to mention I also tried the Giro Prolight techlace but the sizing just didn't fit. The 42.5's were too big and the 42's were a little too tight but they seemed comfortable with easy adjustment FWIW
