PG: Hello Marc, thank you for taking the time to talk to us. Let's start at the beginning: What should people look out for when buying new ski boots?
MA: The most common problem is that people buy boots that are far too big. Only if I have the right size will everything else be right, for example the ankle position.
PG: How can you be sure that the size is right?
MA: You have to try the shoes on, of course, and depending on how much experience you have with them, you have to go to a specialist store where the people really know their stuff. As a typical consumer, I buy a ski boot maybe every 3 to 5 years. So every few years I have an opportunity to find out about ski boots. A good salesperson keeps himself constantly informed, he has completely different experience. A proper specialist store also has a certain pre-selection of good products in its range. I could have a lot more boots in the store, but I only want the ones that really work and that I can sell with a clear conscience. I also make a living from sales, that's for sure, but I make a better living if I can sell something honestly.
PG: If I notice now that my boot is too big and the heel is slipping, there's not much you can do, is there?
MA: You can't make the shell smaller. People buy ski boots like low shoes. They think they need a finger's width of air in front of the toes, which means the ski boot is actually already too big. I stand very differently in a ski boot than in a normal boot. You don't roll off, that's not possible. With ski boots, people don't have the routine and the feeling that you get from other shoes - it either fits me or it doesn't fit. If I then go into a store where the salesperson perhaps doesn't know his way around or doesn't have time, and I buy a boot that I feel fits like my sneakers, then it's usually much too big.
PG: What do you think of foamed inner boots?
MA: If it's done well, a lot. The foaming itself is actually just shaking the foam, the most important thing is the preparatory work. The shell and the footbed must be done properly. If the shoe is too wide, you can fix it quite well with foaming. Foaming a boot that is too narrow doesn't help at all.
PG: I have the feeling that the 27-27.5 shell size is a bit too small for my ski boots, but 28-28.5 is too big as the next largest shell. What should I do?
MA: The larger shell is too big for you, that doesn't work. There are different specifications for shoe sizes. A low shoe in size 38, for example, is a French stitch size, so the difference between the whole sizes is 6.6 mm. Then there are the UK sizes, 4, 4.5, 5, and so on. There is 8.4 mm between the sizes. Ski boots are only produced in Mondopoint, so the difference between the sizes is a full centimeter. So the 28 shell is one centimeter longer than the 27 shell. It's almost like if you're normally a size 41 and then suddenly buy a 43, which is much too big.
PG: So always take the smaller size if you're between shell sizes and then have the boot fitted?
MA: Rather the smaller one, yes. Of course, it also depends on how wide the foot is, how slim the heel is and how the levers are. The lower shells are made in centimeter increments, but the cuffs are often the same over two or three sizes. It can happen that you buy a size 25 shoe, where the lower shell is 25 and the cuff is 24-25.5. If you take a size larger, the lower shell is 26, but the cuff is already 26-27.5. That's quite a big difference, the cuff is much wider at the top and goes up higher. This is often a problem, especially with children, and suddenly nothing fits from one size to the next. You have to try it out.
PG: So now I have a boot and I realize that it pinches. The sports store in the ski resort advertises boot fitting and a fit guarantee. Do you also offer such guarantees?
MA: If someone writes something about a fit guarantee, it should be treated with caution. I've been doing this for 20 years now, I have all the training you can have in this field. The foot is one of the most complex structures in the human body. In addition, personal perception is often very different. I would never dare to give a guarantee. That is dubious. It's like the chef guaranteeing that the food will taste good. In large sports stores with a guarantee, it's often some kind of quick service.
PG: What can you do that they can't?
MA: What counts when fitting ski boots is experience. I don't know everything by a long shot and I'll never know everything, but with every customer, my experience grows and I can work better. You can see the machinery here. The sports stores have maybe one oven, if that. I've tried out a lot and built many machines myself, just the way I want them. They're part of my trade secret!
The whole thing is a learning process and I've broken a lot of shoes at my own expense until I've figured out what works and what doesn't. But I can now say that I get on well with all the usual shell materials and can shape them, for example by stretching, milling and thermoplastic molding. Of course, you can also do a lot to the inner shoes, right up to the complete custom-made inner shoe.
