Cycling Shoes Size Guide - Which Size Do I Need?

Buying your cycling shoes online can be difficult because of the fact that every brand has a different fit. So, to make it a bit easier, we got stuck in at our warehouse and checked, per brand and per shoe, the fit and the length of the shoes. And from that came our sizing advice on the right size cycling shoe, per brand, for everyone.

Because we want you to be 100% happy with the cycling shoes that you've bought from us we now offer Mantels Guaranteed Fit. It allows you to try out your new cycling shoes for 30 days, without obligation. Not good? Then you get your money back!

When can you take advantage of Guaranteed Fit?

Buy your cycling shoes on Mantel.com/uk and take them for a test ride. Don't fit as well as you'd hoped? A bit too tight or too spacious, or are they narrower than you thought they'd be? No Problem!

With Mantel Guaranteed Fit you can just return your cycling shoes, and it applies to all brands. You'll get the full purchase price back and can then buy other cycling shoes from our webshop.

The only condition is that the cycling shoes that you send back should be in a wearable and saleable state. A splash of mud or marking on the mounted cleats is no big deal, so you can mount cleats and ride with them. But we advise you not to take them out on a rainy day or to go cyclo-crossing with them through a sopping wet forest.

A good yardstick for determining what's acceptable is to ask yourself if you'd buy them yourself if you saw them on sale. If the answer is yes, then the chance is good that you'll get your money back for the ill-fitting cycling shoes.

Mantel Sizing Advice - Always the right size cycling shoe

To give you a helping hand finding the correct size we've measured all our cycling shoes on the inside. We also looked at the distance from the heel to the tips of the toes. In doing so, we quickly saw that the same size cycling shoes can differ enormously in length and width from one brand to the next. So we created a sizing table per brand to help you determine which size (in that brand) is right for you. The sizing tables are further separated according to gender and, for some brands, a distinction is made between road cycling shoes and MTB shoes.

To decide for yourself what size cycling shoes will fit you, all you need to do is measure your own foot length in mm. Using that measurement you can see which size, per brand, will fit you. We'll explain how to do this below.

It maybe sounds a bit complicated but it's actually quite simple if you follow the steps below. Want to go straight to the sizing table of your favourite brand? Select from the list below.

• Bontrager cycling shoe sizing table
• Fizik cycling shoe sizing table
• Lake cycling shoe sizing table
• Northwave cycling shoe sizing table
• Shimano cycling shoe sizing table
• Sidi cycling shoe sizing table
• Foot width in relation to foot length

Step 1: Measure your foot

Get an A4 piece of paper and place it on the ground against a wall. Stand on the piece of paper with your heel up against the wall. Draw a line above your big toe (or above the index toe if that is longer) and measure the length in mm. To be sure, measure your other foot on the paper in the same way. Often one foot is longer than the other. Note the length in mm of the longest foot and keep this handy for selecting the correct shoe size.

Step 2: Find the correct shoe size in your favourite brand

Now that you've measured your foot length, you can select it under the foot length in mm range filter to display all suitably sized shoes. Alternatively, you can go to the product page of the cycling shoes you like and select your foot length in mm under What is your foot length in mm?. Does your foot length in mm not appear there? Then there is no available shoe size, in terms of length, that is well suited to your foot.

Using your foot length in mm you can see from the sizing tables below that there can be quite a big difference in the EU sizing between brands. So, go in search of your dream shoes and then check, in mm's, which size comes closest to your actual foot size. These shoes need to fit well!

Step 3: Check that the shoes are the right width

To be certain about the fit you should check the width too. We've classified each shoe according to narrow, average or wide fit. To determine your foot width you need to measure the circumference of your foot.

Do this around the broadest part of your foot as show in the photo. Now look up your foot length in the foot length/breadth ratio table. Alongside your foot length you can look for your foot circumference. You'll then see straight away if you have a small, average or wide foot. Now you can look for the show that fits your foot best!

Do you know that you have a relatively wide foot? Then rather don't choose a narrow-fit shoe. Chances are it'll squeeze or pinch your foot and the shoes will end up having to be returned. We find that shoes classified as ‘average’ width can be worn by pretty much everyone.

Step 4: Order your shoes and don't forget the cleats!

With everything now checked and measured you should now have your cycling shoe size. Get busy browsing and order them from our webshop! The only other thing left to do is mount cleats (these aren't delivered standard with the shoes) and jump on your bike! Need info on mounting and positioning your cleats? Read our blog.
