Cyclocross run-ups through wet grass or loose dirt separate riders who dig in from riders who spin out. Sidi's MTB Toe Spikes thread into the toe section of compatible shoes and bite into soft terrain when you need to shoulder the bike and scramble. The plated steel construction handles the repeated impacts of running on mixed surfaces, and the threaded design allows quick installation or removal depending on course conditions. A set includes 4 spikes, enough for both shoes with two spikes per toe box.

These spikes fit Sidi mountain bike and cyclocross shoes with the appropriate threaded inserts in the sole. Many riders also use them successfully with other brands that share similar spike mounting points, including various Shimano, Lake, and Bontrager MTB models. Check your soles for the threaded inserts before ordering. The spikes work particularly well in mud, snow, and loose-over-hard conditions where the toe area contacts the ground during running sections. For normal trail riding on firm surfaces, most riders leave them off since the added grip isn't necessary and the spikes can feel awkward on hardpack.

If you're racing cyclocross or riding trails where hike-a-bike sections get slippery, these are the difference between confident footing and an embarrassing slide. A touch of thread locker keeps them secure through race-day abuse.
