Performance should not depend on the shape of the foot. That is why Salomon has developed the S/PRO ALPHA 130 with stronger heel fixation and without unnecessary pressure on the instep. This provides outstanding performance and optimal fit for any foot shape. The 98 mm last shoe with a racing-inspired strap with snap closure and fully removable tongue can be completely customized and instantly provides more comfort and performance.

Thanks to the thinner plastic and strategic positioning of the second buckle on the lower shell, pressure is taken off the top of the foot, making it easier to get in and out.

Specs:
• 3D Instep shell and the 45° position of the second forefoot buckle: stronger heel fixation and a more even foot hold, regardless of instep height
• Custom Fit 4D World Cup liner with thermoformable Talyn and removable, two-piece, fully customizable tongue make adjusting instep and fit to your feet easier
• Shell: Custom Shell HD, polyurethane for reliable progressiveness and good power transmission
• Sole: Alpine ISO 5355
• Sensitive footbed
• Energyzer Claw 50 mm power strap with snap closure
• 4 aluminum 3D buckles, screwed
• 10 mm rear spoiler in box
• Shoelaces included in box
• Bolted hinge to align the shank

Technology: 

3 D Instep Shell
Improved fit and easier on and off: With a wider gap between the forefoot buckles, placement of the upper forefoot buckle at a 45° angle, and reinforcement of the foot hold over the ankle. The plastic over the instep is thinner and the hinge point is 10 % wider. 

Custom Shell HD 
The Custom Shell HD process provides a complete fit of the shoe in 10 minutes from top to bottom. 

Power Spine
The shoe features a screw on the outside of the "spine" that lets you turn a metal rod to switch between a "direct" and "progressive" position. The direct position aligns a metal piece vertically so that it connects the cuff to the shell, while the progressive position aligns it horizontally so that it does not connect the shell and cuff directly.
