s-l400.jpg。The Ultimate Walking Shoe Our best got better. As we celebrate 10 years of fan-favorite QUANTUM, we bring you the next generation of heel pain relief: QUANTUM 2. This premium walking shoe features a wider base with a roomy toe box and upgraded KURUSOLE heel support for ultimate foot pain relief. We\'ve refined our signature KURUSOLE technology with increased TPU height for improved dynamic support and heel cushioning. This patented tech flexes with each step to hug and protect your heels for ultimate pain relief. We kept what was already working. QUANTUM 2 features famously wide toe boxes, so your toes can lay flat and your bunions can breathe. That means you can say goodbye to a squished forefoot and walk with the stride that nature intended. QUANTUM 2’s new open-weave mesh brings increased airflow for the utmost breathability. That means you can stay cool and keep fresh through every walk or workout.
