Hi Gabe. There is no leather or suede in the Glycerin StealthFit 20 shoe.
Hi E W, thank you for reaching out to Brooks Running. Our products are produced all over the world, including the United States, Vietnam, Thailand, Taiwan, El Salvador, and Mexico. To create the best running gear in the world we partner with factories that have high levels of expertise in manufacturing quality performance gear, and who do so ethically and sustainably. The mix of product created at each facility can vary based on manufacturing needs, so we aren’t able to specify what products are made where. Each item is labeled appropriately.
Hi Ryan! You might experience a small amount of stretching in the Glycerin StealthFit 20, however it will not stretch significantly. We do have a phenomenal return policy which allows you to try our gear out for your normal runs and walks, inside or outside. If they do not work, we offer free pre-paid return labels on orders to send them back within 90 days for worn items, and 1 year for unworn items. Even if you get them dirty or lose the box we can still take them back with our free labels via FedEx or USPS for a full refund.
Hi Jim! The Glycerin StealthFit 20 in colorway 092 - Black/Pearl/Green Gecko does not feature reflective elements.
Hi Norberto! We offer free express shipping on any orders over $100, and you can see a list of our current promotions here: https://www.brooksrunning.com/en_us/promotions-terms-conditions/.
Hi Norberto! The Glycerin StealthFit 20 does have a removable insole.
Hi Jeff! The Glycerin StealthFit 20 is currently only available in a medium (D) width. The Glycerin 20 in a classic fit is available in a wide (2E) width.
Hi Ravi! The external lacing system acts as an innovative alternative to the traditional eyestay. With this update, we still recommend lacing your shoes how you normally would.
Hi Isaac! For the Glycerin StealthFit 20, the upper is made of our Fit Knit material and the midsole includes our full-length nitrogen-infused DNA LOFT v3.
Hey Rex! The difference between the two is the Adrenaline GTS has GuideRails - designed for runners that experience calcaneal deviation or roll in as they walk or run, while the Glycerin StealthFit 20 is designed without GuideRails for runners that have a neutral or supinated stride. If you're looking for the same support as the Adrenaline GTS, but with more cushion, we recommend the Glycerin GTS 20 or the Glycerin StealthFit GTS 20.
