Mallet Trail BOA vs Izumi X-Alp Summit
Our #1 and #2 picks from The 10 Best Mountain Bike Shoes, compared spec-by-spec with clear pros, cons, and a verdict.
Choosing between the Crankbrothers Mallet Trail BOA and the Pearl Izumi X-Alp Summit comes down to how much time you spend glued to your pedals versus scrambling up remote ridgelines on foot. The Mallet Trail BOA is built from the ground up for aggressive all-mountain and enduro riders who prioritize high-speed foot stability, precise micro-adjustments, and an extended cleat track that mimics downhill setups. On the other hand, the Pearl Izumi X-Alp Summit serves the wilderness explorer, backcountry enthusiast, and bikepacker who require uncompromising off-bike traction and walkability alongside efficient power transfer. Both shoes use BOA dial closures and accept standard two-bolt cleats, yet they approach off-road adventures with distinctly different philosophies: pure cockpit engagement versus all-terrain hike-and-ride versatility. Here is how their stiffness profiles, rubber compounds, durability features, and price tags compare to help you choose the ideal shoe for your trails.
Mallet Trail BOA
Crankbrothers
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

Pearl
The Pearl Izumi X-Alp Summit is engineered specifically for backcountry riders, bikepackers, and trail explorers who demand comfortable off-bike mobility alongside solid pedaling performance. Across independent reviews, this shoe consistently takes top honors for adventure riding because it avoids the ultra-stiff, unyielding sole typical of dedicated race shoes. Instead, it utilizes a nylon composite shank that provides support over the pedal spindle while maintaining natural flex through the heel and toe during extended hike-a-bikes. Durability and traction off the bike are standout features here. The shoe utilizes a heavily lugged, dual-density rubber outsole that grips dirt, wet roots, and loose shale far better than traditional plastic-lugged cross-country soles. The seamless synthetic upper resists abrasion and trail debris, while the single BOA L6 dial offers reliable, on-the-fly micro-adjustments across the bridge of the foot. A lower hook-and-loop strap keeps the toe box snug without squeezing the forefoot, which helps prevent numbness over full-day outings. The trade-off for this walking comfort is a slight loss in pure pedaling efficiency; sprinters and dedicated cross-country racers will notice more sole flex under maximum power outputs. The cleat pocket is also slightly shallower than gravity-oriented shoes, meaning riders must take care with cleat setup to ensure clean engagement with wide-platform clipless pedals. For trail riders who value all-day comfort and scrambling traction above outright race speed, the X-Alp Summit is one of the best values on the market. **Highlights** - Nylon composite 3:1 shank balances pedal support with natural walking flex - Aggressive dual-density rubber lugs for off-bike traction on steep terrain - Seamless synthetic upper minimizes hot spots and resists trail abrasion - Single BOA L6 dial with a secondary lower strap for secure retention - Generous volume in the toe box for long-distance comfort **Watch-outs** - Noticeable sole flex under high-wattage sprints or aggressive pedaling - Cleat pocket design can feel tight with certain wide-body trail pedals - Single dial does not offer two-way micro-loosening

The Verdict
The Crankbrothers Mallet Trail BOA wins this head-to-head for trail riders who demand uncompromising downhill control and cockpit connection. Its premium dual-directional BOA Li2 dial, extended cleat track for rearward foot placement, and stiff, protective chassis give aggressive pilots the platform needed to charge technical descents with confidence. However, the Pearl Izumi X-Alp Summit remains the undisputed champion for true backcountry riders, remote adventurers, and bikepackers. While the Mallet Trail feels like a cycling shoe that can manage short walks, the X-Alp Summit feels like a high-traction light hiker that clips into a pedal, thanks to its articulated toe box and aggressive Vibram ECOSTEP outsole. Choose the Mallet Trail BOA if fast, technical trail sessions and micro-tuned fit are your priorities; choose the X-Alp Summit if your rides frequently feature loose hike-a-bikes and require all-day, off-bike walking comfort on a budget.
