Celrien | Spyndra Self-Locking Flat Sole Cycling Shoe

A cycling shoe built for mountain terrain and all-day riding.

Getting your foot position dialled in on a trail ride can make the difference between a confident descent and a frustrating one. These cycling shoes are designed with a self-locking cleat system, available in both MTB and SPD variants, so you can choose the setup that suits your pedals and riding style.

• Rotary dial for precise fit
• Self-locking cleat compatibility
• Breathable perforated upper
• Aggressive lug grip outsole

Precise rotary dial closure
A rotary dial on the upper lets you adjust the fit with a single twist, giving you a snug hold without stopping to retie anything. The closure system distributes tension evenly across the foot.

Compatible with SPD and MTB setups
Available in both SPD and MTB cleat configurations, these shoes suit a wide range of pedal systems. You can choose the variant that matches your current setup without needing adapters.

Ventilated upper construction
Perforated panels across the upper allow air to circulate around the foot during rides. The breathable construction makes these shoes comfortable for extended sessions in warm weather.

Grippy lug outsole
The deeply lugged rubber outsole is designed for traction on loose, muddy, or rocky terrain. The tread pattern suits both clipped-in riding and sections where you need to walk your bike.
