The Nimbus Series has been the best-selling, high-end neutral trainer for the last several years. The Gel Nimbus 13 should continue to be a huge success as the main updates result in a lighter shoe without sacrificing its premium cushioning.
1. The AHAR outsole used on previous versions has been engineered to be lighter via a new composition high-carbon rubber composition that maintains great durability.
2. The internal heel counter has been replaced by an external Clutch Counter heel construction. This results in a slight weight reduction while also reducing potential irritation around the heel without sacrificing heel stability.
3. The upper is new with some synthetic overlays removed to reduce weight, but the shape is unchanged.
