Bontrager Sonic Womens Road Cycling Shoes White

Bontrager Sonic Womens Road Cycling Shoes White


The Bontrager Sonic Women’s Road Cycling Shoes are designed for all day rides. They use Bontrager’s inForm Race last to give you a high performance fit with a bit of extra room to accommodate your feet swelling on hotter days and thicker socks on colder days. The Sonic is the women’s version of the men’s Bontrager Circuit Road shoe.

The sole of the Sonic shoes is made from a stiff nylon composite with the distinctive PowerTruss. This adds extra stiffness to the soles so you get great power transfer for efficient pedalling.

The Boa Dial ensures a nice fit with plenty of adjustment so you can tighten and loosen the shoe on the fly. The Sonic shoe is designed to work with standard 3 bolt pattern road pedals but can be converted to use 2-bolt SPD style cleats with a Bontrager adaptor plate (sold separately).

If you are looking for a road cycling shoe that will give you efficient pedalling and all day comfort then the Bontrager Sonic is a great choice.
