Technical information

A hybrid sole? Let us tell you more.

When the going gets tough, you may have to push or carry your mountain bike. For better grip and support for both walking and riding, we created a hybrid sole: it is compatible with flat and SPD pedals and draws inspiration from trail shoes for traction on the ground and mountain bike pedals. Not to mention comfort! With the internal and external layers with reinforced lugs, you'll have better support all year round!

Introducing the comfortable, durable ST 500

In addition to giving you traction when walking and pedalling, the ST 500 will also let you ride worry-free: the durable shell limits impacts and abrasion. The elasticated sockliner all along the opening makes it easy to slip them on and prevents dust and pebbles getting in.
To prevent unintended snags, you can tuck the quick-lacing system into the tongue!

Which pedals are compatible?

Which cleats and/or pedals can you use with your shoes?
If you use clipless pedals, we recommend using the following SPD pedals for optimal clipping in:
These shoes are not compatible with Enduro/Freeride-style platform pedals (e.g. SHIMANO SPD M424).
And of course, your shoes are compatible with all B'Twin cleats and pedals!

The story of the ST 500 mountain bike shoes

During more technically difficult rides, you may have to get off your bike. To develop a shoe that gives you traction and support both on and off your bike, our 4-person team worked on different technologies, prototypes, and lab and field tests for over 2 years with 50 different people.
The result is a shoe that provides grip while walking and cycling on MTB trails, as well as comfort while on foot.

One last tip before you hit the road

Cleats explained by our design team:
"When you start mountain biking at an intermediate level, the question of cleats usually comes up. We've created a versatile product that can advance with you. The cleat attaches to the hollow part of the sole without any adjustment: we decided to choose the most common position so that mountain bikers who are starting out with cleats do not use a position that is painful for their knees."
