Fizik

I have low volume, long, relatively narrow feet and these are the best fitting shoes I've ever had. I used the Fizik sizing method and it put me in a 46, which is spot-on. These are the first shoes I've had where I didn't have to cinch them down super tight to keep my foot from sliding forward. In fact, I barely have to tighten the boas at all, and my foot is pretty locked in. I've seen complaints that they're a challenge to put on, and for "normal" feet I can see it. I have no issues.

The downside is that only thin socks work for me. If I wear a thicker (but not thick) sock, they get a bit too tight and uncomfortable. A half-size larger might be better, but then i worry about losing the locked-in feeling. Thin socks coupled with the very breezy mesh upper makes these a summer-only shoe for sure.

I don't love the insole, but the Specialized BG from my old shoes were too thick and made the fit too tight. I haven't tried anything else yet.

The full-retail cost is insane. I got them during a pretty good sale, and would recommend hunting for a sale before plunking down the $$$$. That said, they do tick all the boxes for premium shoes - crazy stiff sole, great boas, super light, and so far they've been easy to care for.

I recently upgraded to the Fizik Vento Argo R3 Adaptive Saddle, and it's been a massive improvement for my endurance rides. I have it mounted on my Canyon Grail Gen 1, and the 3D-printed padding handles the rougher gravel routes around Spokane perfectly. The adaptive zones provide the exact right balance of support and pressure relief, particularly when I'm dialed in on the double-decker bars pushing a hard pace. If you're putting in long miles and need a saddle that keeps you comfortable without sacrificing power transfer, this is absolutely worth the investment.

These would not stand a very cold winter but they are good enough for the pacific north west.

I also don't think they are waterproof enough but can keep you dry on a lighter rain.

Size is true to the number. I would not worry about going higher or lower than what you wear

I've always used shoe covers of varying thickness and insulation with my normal summer road shoes, and at temperatures under 40f, my feet were not protected well enough. I saw these winter road shoes and thought I would give them a try. I normally wear Sidis, and the sizing between the two seems to be pretty close. I went a half a size up to make room for thicker socks, but I could probably have stuck with my normal size. My feet still get cold a bit, but never to the point where I am worried about them. I regularly ride in temps at or below 25f, and these shoes have made it a lot better.
