About the Bontrager Sonic Road Shoe For comfort and performance on a budget, the Sonic Womens Road Shoes from Bontrager are hard to beat. Packed with features usually reserved for models twice the price or more, this is a competitive piece of kit that performs beyond its price point. The inForm Race last is cut to provide a little more room than all-out race shoes, delivering a nice combination of performance and comfort. This is echoed in the moderate sole stiffness, coming in at 7 out of 14 on Bontrager's index, the soles are stiff enough to deliver your power, but not at the expense of comfort.
