I just received this shoes today and I had the opportunity to go for an evening ride under tough weather conditions. Cold and rainy. Very stiff, good looking and very well ventilated. I had to turn around and put my shoe warmers on. These shoes should be very well ventilated in the summer. I can't say much about the workmanship but they seem to be very well made. I also have a pair of top of the line Mavic and SIdi shoes and I would say these are just as good as any other top of the line shoe in the market. Perhaps a step below SIdi Genius 6.6 At $107, these might very well be the best value in the market. I am very satisfied with my purchase. Thank you Realcyclist.
