Hi! The type of soles that you use will not affect the performance of the equipment. The SPX 12 Dual B90 is compatible with WTR soles. The WTR soles are rockered to make walking in your boots easier. Alpine soles are the traditional boot sole option and are also compatible. If you have any further questions, please send us an email at inforossiusa@rossignol.com Thank You! The Look Team

Hi! For our SPX 12 binding, we recommend a 90mm brake for skis that are 90mm wide or less. However, as long as your brakes don't overhang the ski more than 10mm per side, these brakes will work on your skis. If you have any concerns, we would recommend reaching out to the retailer that mounted your skis to see if they can assist you. Thank you! The Look Team

Hi! Our Look Dual WTR bindings are compatible with GripWalk soles when they are in the "Alpine" position. If you would like to contact us directly with any further questions, please send us an email at info@rossignol.com Thank you! The Look Team

Hi, Both of the LOOK SPX 12 Dual and SPX 10 bindings are great. The difference between the two really comes down to two things, DIN range and boot sole compatibility. The SPX 10 has a DIN range of 3-10 while the SPX 12 DUAL has a DIN range of 3.5-12. To figure out what your DIN setting should be set at, we would recommend going into an authorized LOOK dealer and speaking with a Binding Technician. The LOOK SPX 10 is compatible with standard ISO 5355 alpine boot soles. The LOOK SPX 12 Dual is compatible with standard ISO 5355 alpine boot soles, GRIP WALK boot soles, and WTR alpine boot soles. To figure out which binding is right for you, we would recommend looking at what your DIN setting should be and what kind of alpine boot sole you have. For more information, feel free to contact us at inforossiusa@rossignol.com. Thank You! The LOOK Team!
