Runner's World Best Update

" Brooks made a lot of improvements to this lightweight stability shoe, adding a heel cradle to securely hold the back of the foot in place and more gel underfoot to soften impact. The result is a well-padded and supportive landing that doesn't feel squishy. The company also tinkered with the upper, incorporating adjustable straps into the eye-row to allow for a secure, foot-hugging squeeze. Recommended for normal to low-arched runners looking for a soft stability shoe with a great ride."
