These are a big upgrade from my previous Garmont G-Rides. While touring, I used to suffer from blisters on the inside of my heel, just below the ankle bone. With 3 days on the Primes, no problems!
They are very light, the Boa liner closure rocks, and they tour very well. Going down, they're definitely stiff enough for me - a 200lb intermediate skier on K2 Bakers.
The fit required thermo-molding for me. I wear a US 10-1/2, so I went with the 28.0's. I have medium-wide feet and high arches. Out of the box, the boots were painfully tight in the toes, top-to-bottom. Width wasn't an issue. After cooking the liners with a toe cap, I've got a great fit. My heels do move around slightly in touring mode, but I don't think I could fit into the 27.5's, and I haven't developed any blisters yet because of the superior flex.
