Familiarity: I've put it through the wringer
The other reviewers pretty much nailed it: this is a REALLY comfortable shoe. Get them, you won't regret it! I used them for several training sessions on the trainer to get the cleats positioned and then wore them on a 2.5 hour ride yesterday. I thought my other shoes (Pearl Izumi Race Road IV) were comfy but these fit like a glove. The Pearl have BOA with a toe velcro strap yet feel loose by comparison. A few thoughts:
(1) Sizing is maybe 0.5 small if you go by the chart. My feet measure just under 11 1/2 on the metal gauge at a shoe store, which would be 45.5 according to the chart here. I got them in both 45.5 and 46.0. My toes just brushed the ends of the 45.5's, so I kept the 46's. I have needed 46.0's for various Pearls, so maybe it's a cycling shoe thing.
(2) Couldn't see the point of the included set of arch support insoles until I tried them, and boy do they make my feet feel at home! The medium ones work for me.
(3) The laces cleverly "stick" just enough that they don't loosen as you are doing them up. I leave the lower ones slightly loose for extra room in the toe box, and make the upper ones slightly tighter. Double knot the loops and they won't loosen as you ride.
(4) The material is thin and has lots of holes, which is great on hot days, not so much in chilly conditions. Yesterday was only mid-50's yet my toes got a bit cold. So with these shoes you may want shoe covers at temperatures where you would not need them with other cycling shoes.
The only problem with these shoes is that you have to figure out what you will do with the shoes you had before (assuming they are not worn out yet).
