The new Rapid Access entry system with a hinged cuff is really great. The boots are much easier to get on and off then other boots I have tried or used. The hinges are pretty heavy duty and I don't think I will have any problems with them. Rapid Access is available on the Icon line of boots and the Entryx line. It is not available on the Rival Series this season.
As far as a re-fit, you have to go to the retailer to do a re-fit. Although the Hot Form boots come with a boot warmer, it does not get hot enough to re-form the boots. The plug in warmer that comes with the boots is really a boot warmer/dryer. It won't get hot enough to change the fitted shape. By the way, you get this boot warmer with the boots, your ski shop should give them to you when you buy Hot Forms. If they don't, I bet you are getting screwed. You can also get an adapter for an automobile power point plug-in. Warm your boots up on the way to the resort from the hotel or house. What a great idea.
As far as warm and dry, I can only tell you what a PSIA instructor/salesman at my ski shop told me about his Hot Form boots. He tried a prototype pair last spring and used them about 10 days of skiing in Colorado. He said they were the warmest and dryest boots he has ever worn. I bought mine at my local ski shop in Crestwood, IL near Chicago. Snowcrest Ski Center is the name and they are the best shop in the Midwest!! Top notch staff and great selection of merchandise! Tom and his guys at the shop are really great and take good care of me.
As far as cost, well that probably depends on where you live and your relationship with the supplier. I got mine on sale and I usually get a little discount because of my relationship with the shop. They retail for about $650 to $700 give or take a few dollars. I paid bleow $600.
I am sure you will love them if you get them.
