Sierra says: Whether you are progressing on the mountain or through the park the women's Lock BOA will stick with you all the way. It has a soft to medium flex provided by the new articulating cuff and boot design to create smooth transitions when trying new tricks. The Tongue Tension system and Boa Lace offers a lot of support and convenience when lacing the boot up to that exact perfect fit...

Sierra says: The Cool lock will keep what you need secure with its 44" retractable cable, and you will never lock yourself out because it come with 2 keys.
