The Bontrager Sonic Women’s Road Cycling Shoes are designed for all day rides. They use Bontrager’s in Form Race last to give you a high performance fit with a bit of extra room to accommodate your feet swelling on hotter days & 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 Power Truss. 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 & 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 & all day comfort then the Bontrager Sonic is a great choice. Features in Form Race last offers a slightly roomier, high-performance fit Nylon composite Bronze Series sole Power Truss sole design improves stiffness without adding significant weight Boa L6 dial for precise adjustment Stiffness index
- 7 of 14 (compared to 14 out of 14 for the pro level road shoes) Compatible with 3-bolt & 2-bolt SPD-style cleats (2-bolt mounting plate sold separately) Women Specific Design is engineered specifically to yield better fit & greater comfort for women
