I like the shoe more off the bike than my other commute shoes. It has good grip and feels like a running shoe (that doesn't flex). I don't like the placement of the cleat as it doesn't give any clearance to the crank arm. I do prefer it as close as possible with out any interference. This shoe rubs. I am thinking about adding an extra washer between the pedal and the crank arm to see if that mitigates the problem. That said I do like the shoe
I love Fizik shoes. I have 3 pair of Vento Stabilita, 2 pair of Vento Ferox Carbon, 1 pair Vento Powerstrap Aeroweave, 2 pair of Terra Powerstrap X4, 1 pair of Terra X5, 1 pair of Terra X3 and the new Aeroweave X. ALL of those shoes above are 43 and all fit identically. The Vento Proxy in 43 that I own has a TON of volume in the forefoot and the single Boa simply cannot close that up. Length and width are spot on to all my others. But the volume is simply too much. These were clearly built on a high volume last. Sizing down won't work IMO. I had to add a thick insole to make the shoes fit like all the others. Not ideal, but works ok. These shoes are the only pair of Fiziks I own that doesn't have the little rubber gripper dots in the heel which keeps the heel firmly planted in the shoe. I know that all sounds bad. But, they are built very well, have incredible ventilation, are reasonably light and if volume is what you need then they might very well be the ticket. Just be aware that if you have any of the other pair of Fiziks like I listed above, these will NOT fit the same.
I got a pair of the discontinued color/size on sale. These would have been worth the money even if they weren't on sale. I have a wider foot and these are very comfortable. Shimano build quality never disappoints. These have holes for both two-bolt and three-bolt cleats. I use them on SPD pedals. Note that the profile using SPD is pretty high - the holes are not recessed because of the shoes also have three-bolt compatibility. Got a pair of SPD cleat covers to address this issue when walking. Very glad I bought these.
I wont speak to its aero advantage bc that needs to be tested in a wind tunnel on a specific rider. However, my last three triathlons with this helmet have corresponded with some of my top bike performances relative to competitors.
Yes, its a crazy looking thing like something out of "space balls."
The surprising thing to me is how comfortable it is. Well balanced. Ventilation is excellent, even with the vents covered. Visibility is excellent. It comes with two visors - a clear and a dark one. And of course a big case to carry it and both visors in.
