Pros & Cons

Pros & Cons

  • A precisely tuned fit is made possible with the BOA retention system.
  • Optimal adjustment with the BOA closure which is unique in this price range.
  • To use SPD cleats you also need a counter plate that is not included with the shoe.
  • When using SPD cleats, they are not nicely hidden in the sole like with a specific MTB shoe.

The Bontrager Sonic is a combination of a very affordable shoe and beautiful looks. They're fitted with a BOA retention system which you won't find at this price with any other shoe manufacturer. The PowerTruss sole supports both novice and more advanced riders with a decent power transfer efficiency. In short: the Sonic women's road cycling shoes offer an excellent fit and striking new looks but at a budget intended for everyone.

Detailed description size in cm
To help you as best we can in choosing the right shoe size, we measured all shoes ourselves. All you have to do now is measure your own foot length and we will indicate which shoe size fits you best per brand. You can easily measure your foot by placing an A4 sheet on the floor against the wall. Stand with your foot on the paper with your heel against the wall. Draw a line next to your big toe (or the toe next to it if it's longer). Mark your other foot on the paper as well and then continue with the largest foot. Now measure this distance and you have your foot length in cm's! Please note: some suppliers have their own measurement system, which means that what is on the shoe box may differ from what we have measured.

The shoe size you need may vary per brand. This is because certain brands have a smaller or larger last. In addition, we have divided the shoes into narrow / medium / wide. Read all about this on our blog!

Goede aankoop!

Staat niet expliciet bijgenoemd dat je nog extra onderdelen nodig hebt voor het monteren van normale SPD aan de schoen, maar dit is wel nodig!


  • Prijs/kwaliteit
  • Boa systeem


  • Niet zomaar geschikt voor SPD
