The Shimano SM-SH12 SPD-SL Cleats (Blue 2° Float) are road cycling cleats designed for riders who want a more locked-in, performance-oriented feel while still allowing a small amount of natural foot movement.
What they are
These are:
3-bolt SPD-SL cleats
Colour: Blue
Designed for Shimano SPD-SL road pedals
They connect road cycling shoes to pedals for:
efficient power transfer
stable pedalling platform
consistent foot positioning
2° Float (what it means)
The “2° float” allows a small amount of side-to-side movement:
2∘
About 1° left + 1° right movement
Very minimal foot rotation
Keeps your foot close to a fixed position
This is a performance-focused middle ground between comfort and rigidity.
Key characteristics
Low float design
more stable than SH11 (yellow)
less restrictive than SH10 (red)
Balanced knee alignment support
still allows slight natural movement
helps reduce strain compared to fully fixed cleats
Efficient power transfer
better “locked-in” feel than high-float cleats
preferred by more experienced riders
Ride feel
More stable than yellow cleats
Less “floaty” feeling underfoot
Better precision in sprinting and climbing
Still comfortable enough for endurance riding
Best suited for
Intermediate to advanced road cyclists
Training and racing
Riders with a dialed-in bike fit
Cyclists wanting efficiency without going fully fixed
Comparison with other SPD-SL cleats
SH11 (Yellow – 6° float) → maximum comfort, most movement
SH12 (Blue – 2° float) → balanced performance and control
SH10 (Red – 0° float) → fully fixed, maximum efficiency
Bottom line
The Shimano SH12 blue cleats are a performance-oriented SPD-SL option, offering a tight 2° float that improves pedalling stability and efficiency while still allowing just enough movement to reduce joint stress during road cycling.
