Frequently Asked Questions

• How do I choose between Brooks’ cushion, energize, speed, and trail categories for my running?

  Pick by surface and goal: Cushion models like Ghost and Glycerin prioritize plush, high-stack comfort for daily training and long runs; Energize models such as Revel and Levitate use firmer foams (DNA AMP) for quicker transitions during tempo runs; Speed shoes like the Hyperion line use lighter DNA FLASH or tuned plates for workouts and racing; and Trail models (Cascadia, Caldera, Catamount) add rock plates, aggressive lugs, and TrailTack rubber for off‑road traction and protection. Match the category to your typical pace, terrain, and how much cushioning versus responsiveness you want.
• What is GuideRails (GTS) support and who should choose GTS models?

  GuideRails® is a holistic stability system that uses supportive sidewalls and posting to limit excessive inward collapse of the knee and foot while allowing natural motion, rather than forcing a rigid stride. Runners who overpronate or who want added late‑run support often choose GTS versions like Adrenaline GTS or Glycerin GTS for predictable alignment and reduced strain on knees and hips.
• How do the Ghost and Glycerin differ, and when should I choose one over the other?

  The Ghost is a versatile daily trainer with balanced cushioning and smoother transitions for a wide range of paces, while the Glycerin is Brooks’ plushest option—featuring nitrogen‑infused DNA LOFT v3 for maximum softness and higher stack height ideal for long, comfort‑focused runs. Choose Ghost if you want a responsive, do‑everything trainer; choose Glycerin if you prioritize maximum cushioning and a softer underfoot feel for easy miles.
• What trail technologies does Brooks use in shoes like the Cascadia, Caldera, and Catamount?

  Brooks builds trail models with features like Ballistic Rock Shield or a Rock Plate for underfoot protection, the Trail Adapt System’s zonal pods and aggressive lugs for stability and bite, and TrailTack Green rubber for durable wet/dry traction. Models differ by purpose—Cascadia focuses on versatile trail stability, Caldera emphasizes max cushion for long off‑road efforts, and Catamount is tuned for faster, race‑oriented trail performance.
• How should I size Brooks shoes and account for fit differences across lines?

  Brooks uppers use engineered warp knit and mesh that offer breathable stretch, but fit varies by model and whether it’s neutral or a GTS stability version; some lines also come in wide options. Try the shoe with the socks you’ll run in and consult the model’s size chart—many runners stick with their usual running size, but those who need extra toe room for long runs may prefer a half size up or a wide fit if available.
