The original Livewires had a different tread compound (Rubber Kinetics DST 6.0 high grip rubber), just had a look now, and they've upgraded to the same as the Wildcats (soft and grippy 4.0 MAX GRIP rubber). That's a shame that they've taken the option away of having a harder rubber.
(Jan/2019) "The sole of the Livewire is constructed with a rubber blend that was developed with Rubber Kinetics, and it's rated as a 6.0 on Ride Concepts' own grip scale, which is said to equate to a medium-high amount of grip – in this case, the lower the number, the grippier the rubber. For instance, the upcoming DH-oriented TNT shoe rates a 4.0 on that same scale. The sole itself is comprised of dozens of 12mm wide hexagons that interact with a pedal's pins to keep the shoe from slipping around."

It will solidify the Livewire legacy as a reliable shoe to live in, from the singletrack to the bike park, all without compromising style.
