The K2 Spyne 100 Ski Boots give you continued comfort as you try to squeeze as many runs as possible into your day. The boot's progressive flex and K2's Powerfuse Spyne gives responsive feels, whether you're riding on hard packed groomers or on fluffy powder faces.
The Spyne 100s come in at a middle of the road 100mm last, with an uber-comfy Lux Fit Pro liner that can be heat-moulded to give you a precise fit. You can further customise the boot's performance using the Power Wedge to adjust forward lean and by altering dual sided cuff alignment. You'll find the Spyne 100 boots comfortable when walking around the resort too - they come with a rockered sole that's replaceable to extend the boot's life.
Designed to drive your power to the ski
The 100-flex rating gives the boot a nice progressive feel. The Energy Interlock system connects the top and bottom of the boot with no-stress, rivet-free tech. At the back of the Spyne 100s, you've got K2's Powerfuse Spyne to add strength Energy Interlock. This gives you a tonne of flex efficiency and lateral response, no matter where you're riding.
If you're looking for a boot that will keep you comfy all day whilst offering super-aggressive downhill skiing, then the K2 Spyne 100 are a great option.
