All you need to know:

The letters prior to the number designate the gender and the purpose the shoe was designed for.

**Sometimes the model number will start with a “CW” or “CM” which means you have a custom shoe (see below picture).

The numbers on the shoes do not relate specifically to special codes, but they are a way of identifying the different models from each other. Generally speaking, the higher the number, the more technology there is featured in the shoe. This does not necessarily mean that the highest number is the best shoe for everyone.

The letters after the numbers generally designate the color of the shoe. For example, WB would be White/Blue and BK would be Black. There are exceptions to this. For example; in the model MR1123MC, the “MC” designates that it is a motion control shoe. Another example would be WR760ST where the “ST” designates that it is a stability shoe
