I have a pair of these that have been used for two seasons. I do not have the extra set of tongues. Most people here should be familiar with this boot because it is the womens krypton boot, but here is the boilerplate manufacturers info on this boot. Price is $60 + shipping (or local pickup in the Roaring Fork Valley)
"The Dalbello Women's Krypton Kryzma Alpine Ski Boot gives aggressive skiers, top-level chargers and freeriders a close-fitting, responsive boot with unparalleled flex control. The Krypton Kryzma's three-piece Cabrio design locks your foot in place comfortably for precise feel and response while you tear the groomers apart or lap the powder stashes. The Krypton Kryzma's lightweight, yet extremely warm Trufit thermo-liner custom molds to your foot. Taking precise fit to another step, Dalbello molds each of their liners to their respective boot shells before you even see them, which provides seamless interaction between the liner and the boot the way it should be. Out of the box, the Krypton Kryzma is set up as a stiff, hard-charging boot. Swap out the extra set of tongues to soften the flex for freeriding, and replace the stiff bootboard under the liner with a soft one that dampens vibrations and absorbs some of the shock after you huck a record-setting cliff."
