This is common with performance running shoes. Wear them for short distances (1-3 miles) initially to allow the shoe to mold to your foot. Avoid long runs until you are comfortable.

The FuelCell technology is designed to be responsive. It may take a few runs to break in. Ensure you are wearing appropriate running socks. If discomfort persists, consider if this model is the best fit for your preferred cushioning feel.
