text: The shoe should come pre-assembled.  You will have to mount cleats on the bottom; these will typically come with the pedals that you purchase for your bike.  You will need an allen wrench (hex key) to tighten the cleats to the base of the shoe.  Ask your bike shop if the cleats you have will fit the shoe that you have.  If not, you will need to get an adapter from the shop or manufacturer or switch to a different pedal/cleat that is compatible with your shoes.\n\nHope this helps!
