BMW’s GS Adventure boot crossed to Stormtrooper footwear on steroids. With enough armor plating to stop a


rhino, the boots aren’t light, though not heavy, mind you. Right out the box you get a sense that this is top quality, don’t-mess- with-me footwear in a league of its own. Stitching (double-stitched in stress areas), for example, is superbly done and the adjustable screw-on plastic protectors match seamlessly. Plus the anatomical fit is as near perfect as I could imagine. I wear a 10.5 U.S. My 44 Euro Sidis were true to size. The sole is slim, and proved perfectly pro- portional to my foot shape. Even though I wear a pair of knee-length ski socks inside my boot, my toes weren’t scrunched. After my first ride—a full nine-hour jaunt to the Horizons Unlimited Travelers Meeting, in Yosemite, California—my feet felt as fresh and comfortable as the moment I eased into the boots. The Crossfire TA version is a tad wider, but riders with wide feet might also consider going up a size; the boot is available in sizes 7-13. I’ve worn some nice fitting boots in my time, but nothing quite like this. Did I mention the soft inner lin- ing of Cambrelle? I also appreciated the inch-deep, elasti-


cized, softly padded top gaiter seal, which wraps snugly above the calf muscle just below the knee and is lined with Teflon mesh that Sidi claims will prevent absorp- tion of water and sweat. The boots aren’t waterproof, but darn near. Snaking up into the Sierra Nevada, I hit prolonged showers. Nothing heavy, but enough to get a sense that the Crossfire will resist a good dousing. The entire “base material” appears to be


supple leather. Actually, it’s synthetic. Sidi uses its own proprietary material called Technomicro. This composite micro fiber is made from strands less than one-thou- sand the thickness of silk, bonded with special resins to produce a kind of Cyborg leather. Lighter. Softer. Stronger. And, Sidi claims, “water-repellant, quick-drying, breathable and permeable to water vapor… abrasion- and mildew-resistant” and “eas- ier to clean than leather.” Wow! If this were


a real Cyborg I’d date her. The Techmicro base—white in my case


(the Crossfire comes in ten different color combinations)—seals at the top and mid- section with two broad Velcro flaps that draw closed to the boot’s outer side. The base is encased by a flexible injection- molded plastic wrap affixed and hinged to the ankles, and to which are attached three thicker, rigid plastic protectors for ankles, shin and calfs. The calf and shin plates can be adjusted for a wider diameter (22 inches is the maximum) to accommodate fatter legs or knee braces, or to wear your pants inside your boots. The entire leg is thus protected, all-around. Additional hard plastic shells protect the


entire foot area, including a rigid, anatomi- cally shaped, shock-resistant heel and a toe guard extending up to the metatarsal the full width of the boot. The toe guard thick- ens on the inner top side at the shift and brake lever points. The toe of the molded, anti-skid sole is guarded by a screw-in metal plate. Plus, the inner arch features a thick heat-resistant changeable pad affixed by screws atop a larger plastic plate that gives rigidity to the lower boot. The protective covers draw close with a


four-strap cam-lock buckle system that locks to the outer side. Even when wearing gloves, the four metal hasps were easy to mate into their plastic cam-lock buckles, which snapped shut securely. The hasps attach to plastic straps that can be adjusted—shorter or longer—for a perfect fit. I’d read that adjusting the straps is easy. Not! I was flummoxed by what visually seemed like a simple task. I told you… I’m no Dog Star! Fortunately, I didn’t need to adjust the straps. The factory default was perfect. The real beauty of the Crossfires is that


the boots flex. The hinged ankle and flexi- ble vamp (no plate covers the upper mid- sole) let the boot pivot forward, assisted by a smaller hinge further up the calf. The boot is designed so you don’t overdo it. I reckon the maximum flex at about 20 degrees from vertical, giving the boot on the foot a nice “broken-in” feel straight out


the box. A week later, riding off-road in Baja California, the flex proved super handy when standing on the pegs in the rough stuff. I began to understand why many a motocross champ swears by Sidi Crossfires. And yet…while the Crossfire toe profile


is svelte and low-slung, getting under my 1200 GSA’s shifter in first and second gear wasn’t easy. The sole and toe box have vir- tually no flex at all, and the ankle is rigid, too, so I couldn’t “flip” my foot. In fact, it’s hard to feel any contact with the shift and brake pedals. When standing on the pegs the forward flex helped get under the shifter. But when seated, I frequently missed a gear. I even began to shift using the sole lip, lifting the shifter up from the side by raising my leg (after a couple of hours I got muscle ache). I understand all the stiffness is a compromise for better pro- tection, but for bikers who aren’t going to do much off-roading, the lack of flex and sensitivity are major negatives. Plus, Nancy Sinatra surely wasn’t thinking of Crossfires when she sang “These Boots are Made for Walking.” For that, even my Munster-sized Formas proved perfect. All the plate components are replaceable


and, like the Techmicro base, are available in a variety of color combos for the fash- ion-conscious. The SRS model also fea- tures a bolt-on sole so that more aggressive riders can swap worn soles, while others can configure their boot for enduro, super- moto, etc. Interestingly the Crossfire lacks a steel shank; strength is provided by a reinforced and removable nylon insole. Verdict? A superb, feature-packed high-


end boot for serious off-road adventure riders who don’t plan on going urban. You’ll shell out just south of $600, for which you get über comfort and ultra-pro- tection in a boot that many motocross champs acclaim as the best in class. For off- road riding I’m grinning, but maybe I need to invest in another pair of (correctly- sized) Forma Adventures for less demand- ing terrain.
