Bont Vaypor SL road cycling shoes

Bont Cycling size guide

IMPORTANT: DO NOT ORDER THE SAME US / EU / UK SIZE YOU CURRENTLY WEAR.

Because of their carbon “bathtub” construction, Bont Cycling shoes need extra internal length in front of your toes. As a result, your Bont size may be larger than the size of your current cycling shoes.

Ordering too small is the most common sizing mistake.

Already own cycling shoes? Start here:

Use our Brand Comparison tool to convert the size of your current cycling shoes to the recommended Bont Cycling size.

BRAND COMPARISON TOOL

Check the CM / JP / MM number inside your current shoes

The CM/JP or MM number is much more useful than comparing EU, US or UK sizes.

For example:

Your current shoe label: CM 28 (MM 280 millimetres)

Look for an internal shoe length of 280 mm in the Bont Cycling size chart.

If your toes currently touch the front of your shoes, don't try to replicate that fit. Choose a longer internal length.

No other cycling shoes to compare with? Measure your feet.

To find your Bont Cycling shoe size, download and print our measuring sheet in A4 or US Letter size, then follow the instructions carefully.

Stand barefoot and use a straight edge to mark the tip of your longest toe and the widest point of your forefoot. Check your measurements with a ruler to make sure the length and width are accurate.

NO PRINTER?

Place a sheet of paper against a wall.
Stand barefoot with your heel lightly touching the wall.
Put your full body weight on your foot.
Mark the tip of your longest toe.
Mark the widest points of your forefoot.
Measure in millimetres.
Repeat with your other foot.
Choose your size based on your larger foot.

CHOOSE YOUR LENGTH

Example: If your bare foot is 278 mm long, you should choose size 45/10.5, which has an internal length of 285 mm.

CHOOSE YOUR WIDTH

The width chart gives a fit recommendation; it does not show the actual internal width of the shoe.

Measure the width of your forefoot, then add 2–3 mm to find the best-fitting width.

Foot width is only one factor of fit. Foot volume, shape and existing pressure points also matter, so our recommendations include an allowance based on more than 20 years of fitting experience.

If you regularly experience numbness, pressure or uncomfortable pressure points in cycling shoes, consider the Wide fit even if your measurement is close to the upper end of the Standard range.

We don't make barefoot-style shoes – we design our cycling shoes around the natural shape of the human foot.

The racers' choice

The Vaypor SL builds on the success of the Vaypor, adding a race-optimised design, and is made for the strongest riders in the sport.

Ultra-light carbon design

Made from the highest-grade carbon fibre from Japan's Toray and a lightweight Durolite upper, the Vaypor SL is more than 15% lighter than the current Vaypor S – 80 grams per pair in size 42. All while retaining the outstanding power transfer Bont is known for.

Lighter and faster

The new all-titanium hardware allows lighter, durable and trouble-free cleat mounting and adjustment.

Maximum support, two-dial BOA® Li2 Fit System

The new single-layer carbon base and lower-profile carbon front of the Vaypor SL provide outstanding support like the Vaypor 2023, while adapting to an even wider range of foot shapes and types.

The two-dial BOA® Li2 Fit System delivers a precise, secure fit adjustable with micrometre accuracy. The Vaypor SL is made for racers who want to get the most out of everything.

Unshakeable support

Inspired by the legendary Vaypor S, the Vaypor SL offers even more secure foot hold and more stable fixation alongside its incredibly lightweight design.

Lightweight design, outstanding pedalling performance

The light, flexible Durolite upper provides secure foot hold, excellent ventilation and comfortable wear.

The redesigned carbon sole profile delivers the most efficient power transfer and pedalling performance possible while keeping comfort in mind.

BOA® Li2 fit system

BOA Li2 Performance Fit System with two-dial adjustment for a fast, easy and precise fit. Under the BOA Guarantee, the dials and laces are guaranteed for the lifetime of the shoe.

Anatomical design for an even better fit

Thanks to modern anatomical moulding, the Riot 24 adapts to an even wider range of foot shapes, types and widths.

The redesigned anatomical heel holds the heel even more securely while giving more room to the ankle bones.
