I've skied with these boots four times now, for about an hour at a time, and they are great boots. The boots are very comfotable, plenty of toe room, my feet stay warm and dry. The boots are easy to put on and take off. I can lace them up and then forget about them until I take them off to drive home.
These SNS Pilot boots have an extra second pin across the bindings, about two inches behind the regular pivot pin at the toe. These pilot boots snap right into my ten year old Solomon SNS binding with no modifications and they work well together. The old bindings already had a notch to clear the extra pilot pin. I can't say if the pilot feature helps or not as I don't have pilot bindings.
