This is the Burton GENESIS X. It's a ReFlex model, so it can be used with 4x4 boards. This model adds stiffness to the GENESIS, with a stiffer baseplate, highback, and ankle straps compared to the GENESIS. It's not as rigid as the X base, so I think it's easy to use. The manufacturer recommends it for boot sizes from 24cm to 26cm. - Material: Carbon fiber, nylon composite - Color: Black - Features: Embossed laces, short frame design I don't know the model year. Size is S. It has been used, and the highback is a little sticky, but it's not in a condition where it gets dirty. Everything in the photos is included, so there is no original box. Regarding shipping, I usually ship within 1-2 days, but I often travel for work and am away from home. If you are in a hurry, please check in advance via comments, etc. I apologize for any inconvenience.
