Clipless vs. Flat Pedals 

• Clipless: Offers a high level of control while riding fast or technical moves like hopping up onto curbs or over logs. Despite the name, you do clip in and out of them with special cleated shoes.

• Flat (platform): Don’t require clipping in and out, so it's easier to bail in a crash. No special shoes required.

What kind of riding will you be doing? 

• Mountain biking: Flat pedals paired with grippy bike shoes allow easy dismounts; clipless options offer more pedal efficiency, control and power while climbing, and feature 2-hole cleats. 

• Road cycling: Clipless pedals offer the greatest power and efficiency; often feature cleats with a 3-hole design. 

• Recreational riding: Flat pedals or 2-hole cleats make it easier to walk, mount and dismount. 

• Bike commuting: Clipless pedals boost efficiency over long distances; flat pedals let you wear regular shoes instead of cleats. 

What kind of biking will you be doing? 

• Road cycling shoes contain the stiffest soles and cleats that connect to clipless pedals for maximum pedaling efficiency. They're not designed for extended walking. 

• Mountain bike shoes provide added traction on rugged trails, with various designs to work with clipless pedals or flat pedals.  

• Casual bike shoes are good for recreational riders or commuters who want more comfortable, stylish options with bike-friendly features like stiffer soles or clipless pedal compatibility. 

Finding the right fit 

• Choose bike shoes that fit comfortably from the start. A bike shoe that is uncomfortable at first is not likely to become less so. 

• Fit tip: Make sure your toes have enough room to wiggle slightly, your arches feel snug and supported and your heel doesn’t slide up and down. (Feeling some heel slippage while walking is normal.) 

What kind of shoe closure is right for you? 

• Laces will get you the most customizable fit and comfort but get wet and dirty in inclement conditions. 

• Hook-and-loop straps offer quick closure and are more likely to stay secure than laces and usable in muddy, wet conditions. More straps mean a more customizable fit. 

• Notched cam straps with buckles provide the greatest clamping power and security, at a higher price. 

• Dials/ratcheting cable laces deliver an adjustable fit with a quick-release system.
