Good to know
This cycling trainer from Five Ten shares a lot of its features with the original iteration. However, the layout of the closure has been redesigned to deliver a better fit. The BOA system is now located much higher to better secure the instep. Meanwhile, the presence of the strap compensates for the adjusted placement of the BOA. The single strap allows for better fit adjustments near the toes.
Traction. The bottom of the Five Ten Kestrel Pro BOA is lined with Stealth C4. It is a durable rubber that is also innately grippy on various types of terrains. The Dotty tread pattern amplifies its traction, which is great for the hiking part of trail rides.
Pedal power. The sole unit also uses a carbon-infused shank. It reinforces the middle section, so it doesn’t bend when the person pushes down on the pedal. This construction ensures that no power transfer is lost.
Shock-absorption. The Stealth C4 rubber works well in decreasing the shock that travels up the foot. However, this trainer also features an ethylene-vinyl acetate (EVA) midsole that heightens shock attenuation to keep the foot comfortable for more extended periods.
The Five Ten Kestrel Pro BOA features a two-holed recessed cleat system. It is compatible with the following pedals: Shimano XTR M9020, Nukeproof Horizon CS CrMo, Crank Brothers Mallet E, DMR V-Twin, to name a few.
All-weather comfort. The Kestrel Pro BOA uses a weather-resistant top, making it suitable for the varied conditions experienced while trail riding. It is also quick-drying, so it is easy to keep the upper clean. There are micro-perforations on the vamp, allowing outside air to cool down the foot chamber.
The interior is lined with soft textile that prevents chafing. The tongue is covered in mesh, which aids in the ventilation of the footwear.
Lockdown. The Kestrel Pro BOA uses two types of closure: BOA and Velcro strap. The Velcro strap increases the support at the broadest part of the foot. As for the BOA, it allows for quick on and off action. The cable adjusts by merely turning the dial, applying even pressure on the instep.
The Kestrel Pro BOA is designed to fit like your street shoes. It uses two types of closure for fit adjustments, allowing wearers to fine-tune snugness and support.
Inside the trainer is an Ortholite insole. This thin layer works with the midsole to further attenuate shock. It also prevents the foot from moving too much inside the shoe.
