Bontrager Sonic Womens Road Cycling Shoes Purple

Season :

Brand : Bontrager

Code : BTP5516

Weight : 0.00KG

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.


  • inForm Race last offers a slightly roomier, high-performance fit
  • Nylon composite Bronze Series sole
  • PowerTruss 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 and 2-bolt SPD-style cleats (2-bolt mounting plate sold separately)

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
