Sizing Information

The overall fit/size of this new style seems “true” to their published size chart (see below), so if you are comfortable with a certain size from previous boots, then choose the same size. I’d consider the width of the men’s sizes to be normal to slightly wide (D or E).

Our Two Cents

The S-MX 5 boots are aggressive looking race style boots that would be perfect for the serious sport rider or amateur track rider. Protection in this boot includes a hard plastic shin piece, hard armor pieces in the ankle area and reinforced toe and heel boxes. The boot also comes with replaceable toe sliders for the more aggressive rider. Many boots that offer the same type of protection are difficult to walk around in, but these boots have large stretch zones in the front and rear ankle area that allow for comfortable mobility. The top of the toe has some shifter pads on the boots to prevent wearing through the top from shifting. This boot is offered in a “standard”, vented (now sold out), and a waterproof version. All three versions (normal, vented and waterproof) look generally the same. The vented boot (now sold out) makes use of all five visible vents (heel, ankle, shin, side of calf) and also has a couple panels of perforated material on the foot. With the “normal” version, the vents on the heel and ankle are “dummies”, and of course the waterproof boot has all “dummy” vents, but includes a waterproof/breathable liner to keep water out while still allowing for moisture to escape. So this style offers a variety of construction styles for different weather conditions so you can select the right boot to suit your needs.
