Understanding Shimano's DYNALAST Wide Shoe Sizing 

Shimano wide cycling shoes explained

When it comes to comfort and stability on the bike, the right style of shoes with the right fit can make all the difference. That’s why Shimano offers performance road, MTB, gravel, and winter shoes in a variety of sizing options, including wide.

Shoes that feature Shimano’s DYNALAST Wide sizing have an increased volume around the ball of the foot to accommodate a larger range of foot shapes and sizes. However, this added volume and comfort doesn't come at the expense of performance. Instead, the bottom of the last remains the same width as the standard shoe design, which maintains the high-performance technology, pedaling efficiency, and all-day comfort of Shimano's range of cycling shoes.

How does a Shimano DYNALAST WIDE last fit?

Shimano DYNALAST Wide models are not just standard shoes that have been stretched horizontally. Instead, wide sizes feature a larger circumference (about 9 to 10 mm compared to standard sizing) around the ball of the foot. This extra room accommodates more foot girth, especially around the metatarsal pad. Rather than just adding extra width in a two-dimensional way, Shimano’s wide sizing provides more space all around the ball of the foot for more comfort and control.

More space does not mean a loose, sloppy fit, however. Shimano’s DYNALAST Wide technology is anatomically curved to conform better to the natural contours of the foot. It features an adjusted instep height to allow the heel to sit deeper in the shoe so your foot stays snug in the shoe, even on hard, out-of-the-saddle efforts.

Additionally, Shimano’s Surround Wrapping Upper technology does just what it says. It wraps around the foot and allows for greater adjustability to fine-tune the fit for your riding preferences. Together, DYNALAS Wide and Surround Wrapping Upper technology creates fewer gaps between your foot and the shoe, offering a more adaptable fit for longer, faster, and more comfortable rides no matter your foot shape.

Shimano Wide Sizing Right for Me?

For feet that are only slightly wider than standard sizes – D is the standard width for men's shoes – consider increasing shoe length by a half size. For example, go from a size 44 to 44.5 to allow for a bit of molding as the shoe breaks in. However, riders with more substantial variations in foot width should try a shoe with a DYNALAST Wide last.

What if I Still Need Even Wider Cycling Shoes?

Shimano’s Volume Tour Last is perfect for riders who need even more volume to balance comfort and performance on the bike. Built upon the DYNALAST platform, the Volume Last offers more space in the toe, ball of the foot, and heel while still comfortably cradling the foot when pedaling or walking.

Local Shimano dealers have Brannock measuring devices to evaluate feet and can help you determine if wide sizes are the best fit. When in doubt, have an expert measure and evaluate your feet to help pick the right-sized kicks.
