He raced last season in Atomic B9's punched out further to accomodate his forefeet (last measured at least 110 mm). This season he will need more boot to compete better. We're going to try on the Head RS 80/90/100, Atomic M90/M110 and Nordica Speedmachine. Does anyone have other recommendations? Thanks!
Sorry but i don't know of any race boot with a wide last. There are some race (both plug and semi-plug) boots with a wider forefoot. But they are narrow or relatively narrow at the ankle/heel area. These boots require some fitting in the ankle/heel area.
If you want "more boot" for your son, you have two choice IMO.
You could look at some consumer plug boots with a wider forefoot. If he likes the Atomics i would recommend the Atomic RT CS. This boot has wider forefoot than the RT Ti. I tried the Ti (i have size 10 D width forefoot - 100 mm - weighted) and i can tell you that the boot has a generous forefoot. So the CS is even wider than the Ti. The boot comes in different flexes. Softest is 100. Your son is plenty big to flex it. I weigh 155lbs and ordered the Ti 100.
The CS (and almost any other boot with a narrower last than the B's) will require more fitting than the B did. IMO it is the best thing you can do if you want him to have a good boot to compete better.
There is one more thing you can do. Did you know that it is possible to combine the lower shell of the B with an Atomic race cuff? I found this thread
on TGR. Read post #2.
This is exactly what i did to my boots. I took the Tecnica Icon Alu lower shell (medium volume) and combined it with the Tecnica Icon XT-17 race cuff. The lower shell allows ankle and heel articulation, has a comfortable forefoot which allows the big toe to articulate (very important for balance). The race cuff holds my heel down extremely well, the flex is excellent (it has the XT's flex) and it is lighter in weight.
So if the B's lower shell is in great shape you could combine it with a race cuff for better lower leg and heel hold, better flex and increased performance. If you decide to do this, consider a race liner, too. The race liner will hold you son's foot better than the bulky, stock liner. I am using race liners in my boot. With a race liner, i can feel the interior shell contours. I can "feel" the heel, ankle, mid foot, instep and lower leg better. In fact, i can feel from the first met head back.
I don't think that going with the Speedmachine (or another wide boot) will make a significant difference.
