The Bont Vaypor SL is built for riders who demand every possible performance advantage. Combining an ultra-lightweight design with Bont’s renowned anatomical fit philosophy, the Vaypor SL delivers exceptional power transfer, foot stability and long-ride comfort without compromise.

Developed using hand-laid unidirectional Toray carbon fibre, a lightweight Durolite upper and dual BOA® Li2 dials, the Vaypor SL weighs just 200g (size 42) while offering one of the lowest stack heights available in a premium road cycling shoe. Every watt you produce is transferred directly into the pedals with remarkable efficiency. 

Whether you’re racing, climbing alpine passes or chasing your next FTP breakthrough, the Vaypor SL is engineered to help you ride faster for longer.

Built Around Your Foot—Not the Other Way Around

Unlike many traditional cycling shoes that are designed around a narrow fashion last, Bont builds its shoes around the natural shape of the human foot.

The result is:

• Better toe splay
• Increased stability
• Reduced pressure points
• Improved comfort during long rides
• More efficient power transfer

Combined with Bont’s famous carbon chassis, the Vaypor SL creates a secure connection between rider and bike while allowing your foot to function naturally. 

Industry-Leading Carbon Sole

The heart of the Vaypor SL is its completely redesigned carbon platform.

Constructed using premium Toray unidirectional carbon fibre, the sole provides:

• Maximum pedalling efficiency
• Outstanding torsional stiffness
• Lower weight
• Increased stability during sprints
• Exceptional responsiveness

The remarkably low 3.6mm stack height positions your foot closer to the pedal spindle, improving biomechanics, cornering stability and pedalling efficiency. 

Heat-Mouldable for a Custom Fit

One of Bont’s biggest advantages is its proprietary heat-moulding technology.

By gently heating the shoe according to Bont’s instructions, riders can fine-tune the fit around areas such as:

• Heel
• Arch
• Toe box
• Forefoot
• Ankles

This customisation helps eliminate pressure points while improving comfort and foot security.

It’s one of the reasons Bont shoes have developed such a loyal following among cyclists with both narrow and wide feet. 

Dual BOA® Li2 Fit System

The Vaypor SL features the latest dual BOA® Li2 Performance Fit System, allowing precise adjustment across the forefoot and upper independently.

Benefits include:

• Fast micro-adjustments while riding
• Even pressure distribution
• Secure heel retention
• No hot spots
• Consistent fit throughout long rides

Every BOA® dial is backed by the BOA Lifetime Guarantee, providing confidence for years of riding. 

Lightweight Without Compromise

Compared with the previous Vaypor S, the Vaypor SL reduces weight by over 80 grams per pair while maintaining Bont’s renowned stiffness and support.

The new Durolite upper improves:

• Breathability
• Foot hold
• Long-ride comfort
• Durability

The result is a race-ready shoe that’s lighter, cooler and more comfortable than ever before. 

Optimised Cleat Positioning

The Vaypor SL includes an extended slotted 3-bolt cleat mounting system, allowing greater fore-aft adjustment than many traditional road shoes.

This makes it particularly valuable for:

• Professional bike fits
• Riders using mid-foot cleat positions
• Long-distance cyclists
• Riders refining pedalling efficiency

Perfect For

The Bont Vaypor SL is ideal for:

• Road Racing
• Climbing
