Got a stellar deal on these from BTD. They've been great for casual, scenic all-road type rides and I've also worn on some light singletrack. Very lightweight and great airflow in the heat. No they're not super stiff and not marketed as such, but they're still adequate to grab the occasional PR on local climbs. I don't feel that I'm giving up much in terms of performance and I usually do a ton of climbing on my rides. Heavily padded tongue does take up some volume when first trying on, but settles down after a couple wears. I ordered my normal Giro size. Oh yeah, Midnight blue looks the bomb.
Theses shoes are narrow, which is good for my feet. The insoles are well-padded, but the fabric is generally thin, which is good! They run small. I bought a 39, which are a little long for my feet; I normally (and reliably) wear a 38. Great low-tech buy for a cyclist.
