The Crankbrothers Mallet Trail BOA stands out as the premier all-around clipless shoe for modern trail riding, balancing pedaling efficiency with the compliance needed for rocky hike-a-bikes. Independent reviews consistently praise its extended cleat track, which allows riders to position cleats farther back toward the midfoot for greater stability on steep, technical descents. It bridges the gap between lightweight cross-country slippers and overly bulky downhill boots, making it a versatile choice for aggressive singletrack and all-day backcountry epics. Constructed with a synthetic upper, reinforced toe box, and Crankbrothers' proprietary MC1 high-friction rubber, the shoe clips in and out predictably with various pedal systems while offering secure footing when dismounted. The single BOA dial provides fast, precise micro-adjustments, paired with a hook-and-loop strap to lock the forefoot down without creating harsh pressure points. Reviewers note that while the shank is stiff enough for efficient energy transfer during long climbs, the flexible toe zone preserves a natural gait when scrambling up loose trail sections. At roughly 844 grams per pair, the shoe carries reasonable weight for an armored trail model, though it runs toward the premium end of the price spectrum. Breathability is adequate for mild to warm weather, but riders in sweltering conditions may find the armored upper runs warm. Overall, it earns top marks across leading review outlets for its refined fit, dependable retention, and versatile trail demeanor. **Highlights** - Micro-adjustable BOA Li2 dial combined with a forefoot hook-and-loop strap - Extended cleat channel for aggressive, rearward cleat placement - MC1 mid-friction rubber compound designed for smooth entry and exit - Reinforced toe cap and synthetic upper for rock-strike protection - Flexible toe zone aids walking and hike-a-bike sections **Watch-outs** - Premium retail price sits higher than many direct competitors - Upper construction retains heat on hot summer rides - Single BOA design does not allow independent upper and lower tensioning

The Crankbrothers Mallet Trail BOA sits at the intersection of rugged gravity protection and cross-country pedaling efficiency. Designed specifically for aggressive trail and all-mountain riding, this clipless shoe addresses common shortcomings of conventional trail footwear by pairing a moderately stiff pedaling platform with an extended cleat track. This design lets riders push their cleats rearward toward the midfoot, a position widely favored for stability on steep descents and rough terrain. Retention is handled by a micro-adjustable BOA dial alongside a lower hook-and-loop strap, distributing tension across the foot without pinching. Down below, Crankbrothers utilizes their MC1 rubber formulation in the outsole, striking a calculated balance between clipping clearance on the pedal body and traction when scrambling over rocks. The sole incorporates a slight rocker and toe flex, making off-bike transitions manageable on steep hike-a-bikes. At roughly $240 and 844 grams per pair in size 43.5, the Mallet Trail BOA is an investment piece aimed at riders who spend long hours on technical singletrack. It provides solid impact protection around the perimeter, though the heavily reinforced construction means it runs warmer than minimalist cross-country slippers in high heat.
Who It Is For
The Mallet Trail BOA suits all-mountain and enduro riders who want a secure, pedal-efficient shoe that will not punish them during rocky hike-a-bikes. Riders who favor a midfoot cleat placement will appreciate the elongated cleat channel, which accommodates positions farther back than standard cross-country shoes allow. It fits best with trail riders who tackle technical terrain, drop into steep descents, and need sufficient armor against trail debris without resorting to a heavy, downhill-specific boot. Conversely, dedicated cross-country racers seeking ultra-stiff carbon soles to shave grams will find the construction heavier and more flexible than their race-day needs dictate. Casual riders sticking to smooth fire roads may also struggle to justify the premium price tag.
Materials and Outsole Build
Crankbrothers builds the upper using durable synthetic materials paired with reinforced armor across the toe box and heel cup to deflect rock strikes. Underneath, the brand deploys its proprietary MC1 rubber compound, engineered with a mid-friction profile designed to guide pedal cages smoothly into engagement rather than snagging. The cleat box features tapered ramp entries that facilitate intuitive engagement across Crankbrothers, Shimano SPD, and other two-bolt systems. While the central shank provides adequate torsional rigidity for efficient power transfer through the pedal spindle, the toe and heel zones feature targeted directional lugs and tuned flexibility to provide dependable foot purchase when scrambling across loose dirt or slick granite.
Pedaling and Walking Balance
On the trail, the balance between pedaling stiffness and foot mobility defines the shoe's character. Independent reviews highlight that the shank is firm enough to stave off arch fatigue during extended seated climbs without acting like an unyielding plank. That tuned compliance pays dividends when forced off the bike; the articulated toe section allows for a natural walking gait during technical hike-a-bikes, unlike the awkward clomping common in pure cross-country footwear. Cleat entry and release remain consistent across various trail pedal systems, though the rubber surrounding the cleat pocket can occasionally require spacer tuning depending on pedal pin height and cage dimensions.
Sizing and Fit Adjustments
The shoe relies on a BOA Li2 dial for incremental tensioning over the instep, paired with a forefoot hook-and-loop strap to anchor the toe box. This dual-closure arrangement allows riders to isolate midfoot tension from the forefoot, accommodating varying foot volumes and preventing numbness during long descents. The heel pocket is sculpted with directional lining to minimize heel lift under power. In terms of overall fit, the shoe trends true to size with a medium volume throughout the midfoot and toe box. Riders with particularly wide feet may experience some lateral squeeze along the forefoot reinforcement, making trying them on with trail socks advisable.
Comparable Market Alternatives
At roughly $240, the Mallet Trail BOA competes directly with premium trail models like the Shimano GE9 and the Five Ten Kestrel BOA. The Shimano GE9 offers comparable armor and a similarly extended cleat track, often delivering a slightly wider toe box that suits broader foot shapes. The Five Ten Kestrel BOA prioritizes a stiffer, more traditional cross-country pedaling feel, sacrificing some off-bike walking compliance compared to the Mallet Trail. Riders looking to spend less might consider standard lace-up options, though they sacrifice the quick on-the-fly micro-adjustments provided by Crankbrothers' BOA and strap integration.
Durability and Real Trade-Offs
Every piece of protective gear involves compromises, and the Mallet Trail BOA is no exception. Its protective synthetic upper and reinforced perimeter keep rocks and trail grit at bay, but that robust build naturally reduces airflow. On hot summer climbs, testers and aggregate reviews note that the shoe retains heat, making it less ideal for sweltering midsummer epics. Additionally, while the synthetic materials resist abrasion, the rubber around the cleat pocket will inevitably show wear if paired with aggressive, pinned trail pedals. Finally, the $240 price point places it firmly in the premium bracket, meaning buyers must truly value the extended cleat track and dual retention system to justify the investment.
How we picked
