Full Tilt First Chair Ski Boot - Men's - 2009 BCS

Nope, stiffer. The Bubble Bees used the dual density #6 tongue, which is now featured in the FT Classic. These us Full Tilts stiffest #10 tongue- same tongue that is used in the Seth Morrison Pro model.

You can't get a good idea of the fit until you mold the liners. I have a larger calf and can't put the unmolded boots on. But they are heaven after I get them molded. Also- a good bootfitter will make this boot fit. And you won't ever look back.

it will fit exactly the same. try going with a Dalbello IL Moro.

I am also a female with narrow feet, although I am smaller than you (5'5", 130lbs)
The First Chair and womens Soul Sister both have a 99mm last.
I did a run the 2010/2011 full tilt womens Soul Sister at Stratton last year and I found it wide for a narrow boot, but they were also a little big.
I measure a 24.5, wear a size 8 sneaker, and I wear a 23.5 ski boot.
They only had the 24.5 and it was too big. It was also a little long, so it was probably the wrong size for me anyway.
I ski the Salomon Poison. It has a flex of 90 and a 98mm last. It is the Women's equivalent to the men's Shogun (flex 100). I have also tried on the Salomon Instinct CS in a 24 and I found it too wide, even though they are both Salomon and have the same last. I used to have the Salomon Scarlet size 24, which I found to be narrower than the instinct. The Scarlet is discontinued (replaced by the poison).
I have practically no room in a shell fit in my poisons but it doesnt feel too short at all, even though i wear a size 8 in a sneaker and they my boots are a 23.5.

The liner: Looking at the liner, it appears thin, but wearing the boot, it feels soft and cushy, not in a bad way like a beginners boot. They feel supportive and stiff.

You might want to try going down a shell size, but be careful that that shell size isn't softer. I would also recommend the whole size and not the half size because they both have the same shell, but the whole size has a thicker liner. Atomic boots are not like this (ie. the 24.5 and 25 will have the same shell). Dalbello might be the same way.
Since you were in world cup boots, especially a boot with a flex of 130, I will assume that you are a strong skier. The 24-25.5 should have the same upper shell so that should be the same stiffness. A larger size will be stiffer than a smaller size. My 23.5 are made using the top part of the 22-23.5. I feel like it is a little too short, but they are the closest to perfect I have ever found. I can't flex them when it is really cold, but I like that I can't flex them, but I am also smaller than you.

A woman's boot will be narrower than a men's boot of the same last, but world cup boots are probably different.

A bootfitter might be able to make the Soul Sister fit. The soul sister has a medium flex (6 on full tilt's scale of 10) but you can buy a stiffer tongue to make it stiffer.
If you can find the Scarlet in your size (flex of 85, but I couldn't flex it and I found it to be stiffer than the Salomon Idol 8CS, also with a flex of 85), try it on. Also try the poison, if you can find it.

You should try the Salomon Ghost as well. They are 98mm and they are built on the Salomon race last. The stiffness is 130 and the 2 buckle construction may be better for your forefoot issues

I had the same problem at first. I didn t mold them and just rode them unbuckled for a couple of days. Of course there was some pain at first just like any new ski boot. After 4 days i could buckle them up and even go a couple notches down. The most comfortable boot I have ever worn with the highest performance and the warmest. I have the 2010 FT Konflicts. Give them a little time, sooo worth it. I ve been skiing for 30 years and finally a comfortable boot that performs like a race boot. They rip!!

The window between 130 to 160 is huge! I'm curious to see the actual stiffness of 160's if some brands claim for it. At Salomon, the 130 are the stiffest and correspond to our race boots and big mountain boots (Ghost and X3)

That is about the same ball-park. The 10 is the stiffest that Full Tilt makes, so can be compared to downhill racers or big mountain boots.

That's roughly a 25.5 shell (296mm), which would be in the 7.5 range. Buy 'em up!
