Giro Shoes Width Options
Giro offers different width options for their shoes, so there’s an option for everyone, and you don’t need to worry if your feet are a bit wider.
Performance Fit
The Giro performance fit supports low-volume feet and is the most common option. We would recommend getting this width option if your feet are a narrow to medium width.
High-Volume Fit
The Giro high-volume fit is specially designed for wider feet (from D to EE) and offers greater overall volume and an extra-tall instep. This one is also a good option for those who use a custom orthotic since they’re much wider than the normal performance fit Giro shoes.
If you’re unsure about width letters, check out our guide on what does shoe width letters mean.
Women’s Performance Fit
Since women tend to have narrower feet, the women’s performance fit is designed with a lower volume than the standard performance fit shoes and have a narrower heel cup and forefoot width..
How To Choose the Right Giro Shoe Size
Here’s how you can measure your shoe size at home to be prepared. This way, you’ll know which Giro shoe size will fit you perfectly before you head in-store or if you plan to order them online.
What You’ll Need:
- A blank piece of paper.
- A pencil.
- Socks of medium thickness.
- A ruler or measuring tape.
Method
Take a blank piece of paper that’s a bit larger than your feet, and place it on the floor. Put your foot on the paper, and draw a mark on the top of your longest toe and at your heel. Take a ruler or a measuring tape, and measure the length between the two marks.
To know which shoe width to choose from, take a measuring tape and measure the widest part of your foot.
After you’re done and have all the needed measurements, check the size charts above to determine which size Giro cycling shoes will fit you best.

Sizing Tips and Tricks For Cycling Shoes
The following tips and tricks are good to know if you’re planning on buying a pair of cycling shoes and can help you choose the right size:
- Cycling shoes should feel comfortably snug around your feet.
- Unlike other footwear, cycling shoes will not stretch over time since you’ll be using them for cycling and not walking. So don’t buy shoes that are a bit too tight thinking you’ll stretch them out a bit.
- Your largest toe should touch the front of the shoe, but you shouldn’t feel any pressure, and you should still be able to move your toes around.
- Your heel shouldn’t move up and down and slip around easily while you’re wearing the shoes.
- It’s best that you try half-sizes until you find a cycling shoe that fits you well.

What Happens If Your Giro Shoes Don’t Fit?
Getting the correct size for cycling shoes is important for your cycling efficiency as well as for your comfort and health.
If They’re Too Big
Oversized cycling shoes will rob energy from you while pedaling since your feet will be moving inside the shoes too much. Having cycling shoes that are too big might also cause hot spots, numb feet and blisters.
If They’re Too Small
If you have cycling shoes that are too small and too tight around your feet, the discomfort will make it harder for you to apply full pedaling pressure. The longer you ride, the more pain and discomfort you’ll experience. You can also get blisters and a feeling of tingling or numbness in your feet, especially the toes.
Frequently Asked Questions
Do Giro Shoes Run Small?
Some models might run half a size too small, so it’s best to read online reviews for the model you want to buy. Generally, Giro cycling shoes run true to size, so when you’re deciding what size to get, go with your normal shoe size. If you’re between sizes, then it’s best to size down half a size as most cycling shoes are designed to fit snug around your feet.
Are Giro Cycling Shoes Suitable For Wide Feet?
Yes, Giro actually offers several of its cycling shoes in a high-volume fit, for foot widths from D to EE, with an extra-tall instep.
Should I Buy Cycling Shoes a Size Bigger?
A lot of people tend to size up on cycling shoes because they’re generally narrower compared to normal shoes, so they’ll size up because of the width and not the length.
However, you should consider sizing down when buying cycling shoes if you’re between sizes. You’ll not be walking and moving around with them, so you don’t need the extra room as you would with walking shoes. Remember that cycling shoes should feel comfortably snug, and you shouldn’t have too much room in your toe box as you would with normal shoes.
The Bottom Line
When buying a new pair of Giro cycling shoes, it’s very important to get the perfect fit. Otherwise, you could experience a bunch of problems and difficulties, especially on the longer bike rides.
Giro cycling shoes should feel comfortably snug but not too tight, especially around your toe area. This might cause you pain and discomfort and make it harder to apply full pedaling pressure.
