Black Diamond's Distance Spike Traction Device is one of the few set of spikes specialized for trail running. Most spikes like this one fit hiking shoes and trail running shoes alike, but the addition of a softshell toe cover gives trail running shoes a more secure fit and additional weather protection. The Distance Spike includes 14 stainless steel spikes for improved traction on icy surfaces. It only weighs 4 ounces and can pack into pockets on most running vests.
