How to build leg muscles for fall shoes?

Couple of things. If you are looking to tone then you want to lift lite weights with increased repetitions. If you are looking to build strength and muscle mass then you want to use heavier weights. If you have access to work out equipment then you can do leg presses, leg curls, squats, leg lifts.
Leg muscles. Can be built by doing leg excercises i.E weights of the lower extremity, calf raises etc. I assume you are asking to make them look good as one should not in general have to build muscles for any type of shoes.
