Short answer
The Adidas Galaxy 6 serves as a definitive case study in democratized comfort, offering significant lateral relief through its exceptionally wide 107.2 mm forefoot construction. While the model is marketed as True to Size (TTS), our biomechanical analysis reveals a slightly short last that may require a half-size adjustment for high-volume feet or active running.

Fit Notes
- Nike Revolution 6
- The Nike Revolution features a narrow, tapered fit (93.1 mm width). Because the Galaxy 6 is nearly 14 mm wider, you can stick to your true US size to gain significant width relief without needing to size up for lateral space as you might in Nike.
- ASICS Gel-Contend 8
- While ASICS runs consistently TTS in length, it typically features a more restrictive toe box. In the same size, the Galaxy 6 provides a roomier internal volume (81.8 mm at the big toe) and a more accommodating feel for natural toe splay.
- Nike Air Force 1
- The Air Force 1 is a voluminous lifestyle sneaker that runs notoriously large. Transitioning to the athletic, performance-oriented last of the Galaxy 6 requires a full size increase (1.0) to account for the snugger mesh upper and shorter last length.
- Adidas Superstar
- The Superstar runs slightly large due to its lifestyle design. The Galaxy 6 utilizes a more technical, performance-tapered fit; therefore, a 0.5 size increase from your Superstar size is recommended to maintain optimal toe-room.
Sizing FAQ
Does the Adidas Galaxy 6 run true to size?
The Galaxy 6 is generally True to Size (TTS), but laboratory and user data indicate the 'last' (the foot mold) runs slightly short. For casual wear or vocational standing, your usual size should suffice. However, runners or those between sizes should consider sizing up by 0.5 to allow for foot swelling and to prevent the toes from hitting the front of the shoe.
Is the Adidas Galaxy 6 good for wide feet?
Yes, it is excellent for wide feet. With a measured forefoot width of 107.2 mm, it is substantially wider than the industry average of 98.5 mm. The engineered mesh is flexible enough to accommodate D and 2E widths comfortably even in the standard width model, providing essential lateral relief.
How is the arch support on the Adidas Galaxy 6?
The Galaxy 6 is classified as a neutral trainer, meaning it does not have aggressive medial posts for overpronation. However, it features a stable, rigid platform and a removable OrthoLite sockliner. This makes it highly 'orthotic-friendly,' allowing users to easily swap the factory insole for custom medical-grade arch supports.
