Try not to look at the labels race or all mountain.
Just about every manufacturer has a recreational race boot (98mm last) and a top of the line all mountain boot, the only difference
being the color of the plastic they are shot in.
Be concerned with appropriate flex and fit for YOU.
For example, I don't race, and I ski in an Atomic RT Ti, 95 mm last for my very slender foot and lower
IN A 100 FLEX! I can flex it both on trail and off. If I were to race, it would work perfectly for me.
My friends would all crush that boot, but for me it is perfect.
Only 2 things to know about boots, you can make them softer but not stiffer, and you can make them bigger but not
To give you a real world example, my 2 most regular ski partners happen to race the town downhill here at Snow King, and finish top 10 in the pro division every year.
One skis in Lange plugs, the other in the Rossi all mountain boot 130 flex. True this is actually a Super G, but they do record speeds
in the low 60s. Would the guy in the Rossis prefer a stiffer boot for this? Sure, but he isn't going to buy a boot for 3 days out of the year
when he can make the lesser boot work.
