Salomon Scarlet Ski Boot - Women's - 2008 BCS

These boot work great for a narrow foot. I have trouble finding boots narrow enough and these are great for narrow feet. I got these in s size 24 but they seemed a little big for me. That doesn't mean that they run big, but for me they felt big. I wanted to exchange them for a 23 or 23.5 but they were out of stock in that size so I got the Salomon poison in a 23.5 and I love those. I would love to be able to ski these in a smaller size but they were out of stock. I highly recommend these boots for narrow feet.
For flat feet (or a high arch) I recommend a custom foot bed or a supportive foot bed such as the Aline footbed ( http://www.backcountry.com/outdoorgear/ALINE-Footbed/ALE0001M.html?CMP_ID=SH_FRO001&CMP_SKU=ALE0001&mv_pc=r126 ). Flat feet need support and when they don't have support it can cause pain.

Yes. It has a 98mm last and a flex index of 85.

The boot has rivets in the back behind the heel that can be removed to make the boot softer. If that isn't soft enough than a boot fitter can make them softer by cutting a certain part of it. The price is right. Go for it.

I would recommend that maybe you look into something with a softer flex, which is geared more for intermediate skiers, or else something that is really customizable. I love Dalbello, and I got my girlfriend into them, and she says that with all the features in the women's boots, anyone can use a pair.

My girlfriend rocks this boot, and she has a medium-ish width foot, and she says it fits very nicely for her. Your situation might be a little different, so I would recommend heading in to a store that carries them, and trying them on. This is pretty much the only way to be certain.

I would recommend taking it to a boot fitter, who can do this for you.

My mom has a high arch on the top of her foot, not meaning on the sole, but on the top of her foot, above where the arch is. We both wear the same size shoe (she is a little bit smaller) and she couldn't get her foot into my Scarlets because of the height of her feet. They are pretty easy for me to put on, but kind of hard to take off because of the tightness above the arch area on the top of the foot. They are very low volume, which I like, but sometimes the overlapping part gives me a bruise when I take them off if I am not careful. They are still a great boot. If your arch problem is similar to hers, then you might not be able to get these on. I have narrow feet and my mom's feet are even narrower than mine. These are good for narrow feet. You should get custom footbeds to help solve your arch problem.

The Scarlett is a great all-terrain/multi discipline ski boot. It is also quite comfy in fit with good interior padding which may help you to avoid the shin bang you are experiencing. For your height, weight and athletic ability, this boot is soft/light in feel but skis with precision and strength, and should be a perfect versatile boot for you.
