Lighter than my LG Carbon HRS
I absolutely like the light weight of the shoes. Plus it matches my Castelli Duran kit. I definitely felt the ventilation on my first ride because I was caught in the rain. I could actually feel the cold rainy air rushing through my feet. Therefore, I would expect my feet to be thoroughly ventilated on hot days. Totally loving it. Now I have 2 pairs to shoes to match my different kits. Hurray!
