Read the complete model name
For shopping purposes, GTS identifies the Brooks models featuring GuideRails. Keep that suffix in your search and on the box you inspect: a related model without it may have a different construction. The generation number matters too. A familiar family can receive changes to cushioning and fit between releases. If you are replacing a favorite, write down the full name and width before looking at offers. This avoids treating a newer version, a neutral relative or a different width as an identical replacement.
When comparing listings, photograph the size label on your existing pair. It preserves details that a remembered family name can miss.
Daily running and plush options
Adrenaline GTS is the everyday reference point in this range. Brooks describes Glycerin GTS around a plusher cushioning experience with structured support. That makes them a useful first contrast when your main question is underfoot feel. Our suggestion is to try them for the same intended activity rather than assume the higher-priced pair is an upgrade for every runner. Compare heel hold, the pressure around the middle of the foot and the transition at your normal easy pace. A shared support system does not guarantee a shared internal fit.
Broader platforms and a faster alternative
Brooks describes Beast GTS as a men's model and Ariel GTS as a women's model, both with broad bases. Addiction GTS is described as having room for orthotics, though your actual device still needs a fitting. At a different end of the shopping brief, Hyperion GTS 2 is presented as lightweight and intended for a fast feel. These options should not be arranged as a simple good-better-best ladder. A broad platform, insert accommodation and a workout role answer different questions, so begin with the role you actually need.
Narrow the range without losing the fit question
Choose one reference pair and one meaningful alternative. If you like Adrenaline but want a different cushioning sensation, compare Glycerin GTS. If upper space is the problem, investigate widths and internal shape before shopping for speed. If your daily shoe is already settled, a lighter model can be considered for a separate session. Check availability at the exact size and width level; color options can conceal different stock. Finally, keep a record of what worked and what did not. That short note will be more useful at the next update than simply remembering that you wear Brooks.

Are Beast and Ariel interchangeable listings?
No. They belong to different size and fit ranges. Verify the actual model, sizing and width rather than generating a men’s or women’s variant from the family name.
Does GTS mean waterproof?
No. GuideRails is a support feature. Waterproof construction is a separate product characteristic and must be verified on the exact listing.
