The Science Behind the Glycerin Flex: Brooks’ Director of Product Reveals How Great Shoes Are Really Made

The holidays are in full swing, and we're pulling back the curtain on one of the most anticipated running-shoe launches of the year. The brand-new Brooks Glycerin Flex is here, and we have Nikhil Jain, Director of Product Line Management at Brooks Running–and the mind helping steer innovation behind the brand–joining us to break it all down. The Glycerin Flex is an all-new, highly cushioned running shoe debuting in early 2026 that offers a smoother, more flexible ride compared to the standard Glycerin. Nikhil Jain himself brings unmatched insight into the art and science of building world-class running shoes. From line planning to forecasting; from creative problem-solving to leading teams that shape what millions of runners feel underfoot; he offers a rare look into Brooks’ product engine. Whether you’re a shoe nerd, a data-driven athlete, or just curious about what makes the Glycerin Flex so different, this is required listening. If you’re interested in delving into the experience of the future of cushioning in running straight from the source, this is the place to be. Tap into the Nikhil Jain Special.
