Unlike most aluminum shoes, the Equi-Librium ™ Aluminum does not have a steel insert.  Extensive testing proved that Equi-Librium ™ shoes without steel inserts have significantly improved wear patterns, preserving the design advantages for the life of the shoe.  When a fraction of a second is the difference between a win or loss, the Equi-Librium aluminum makes the difference. 
 
Available in fronts with left & right patterns.
