Short answer
The Adidas Pureboost 23 is a versatile daily trainer that perfectly balances 69.5% energy return with a highly breathable engineered mesh upper. While it fits True to Size (TTS) for the majority of users, its standout feature is an exceptionally spacious toe box measuring 102.4 mm at its widest point, offering significant lateral relief for runners with broader forefeet.

Fit Notes
- Nike Air Force 1
- The Nike Air Force 1 possesses massive internal volume and runs approximately 0.5 to 1.0 size large. Because the Pureboost 23 features a more athletic, snug midfoot lockdown and adheres to standard length benchmarks, users should size up a half-size from their AF1 size to maintain proper length and comfort.
- Nike Pegasus 40
- Nike utilizes a narrower, performance-locked fit compared to the neutral last used in the Pureboost 23. While both models are technically True to Size in length, the Pureboost 23 will feel more accommodating in the forefoot; therefore, you should stick to your standard size for a consistent fit.
- Adidas Samba OG
- The Samba OG is characterized by a narrow, long, and rigid leather fit. The Pureboost 23 is far more forgiving due to its stretchy mesh upper and wide 102.4 mm base; if you normally size up in the Samba for width, return to your true length in the Pureboost for optimal lateral relief.
- Adidas Ultraboost Light
- As the Pureboost 23 is a 'takedown' version of the Ultraboost series, it shares a very similar internal length. Users transitioning between these two Adidas models should stay True to Size, though the Pureboost provides a slightly more breathable engineered mesh compared to the UB's Primeknit.
Sizing FAQ
Does the Adidas Pureboost 23 run true to size?
Yes, based on community feedback and laboratory data, the Pureboost 23 is widely considered True to Size (TTS). While the supportive engineered mesh may feel snug during the first 15-20 minutes of wear, it quickly molds to the foot's specific anatomy for a perfect fit.
Is the Adidas Pureboost 23 good for wide feet?
The Pureboost 23 is an excellent candidate for wide feet, boasting a generous 102.4 mm width at the forefoot and 80.4 mm at the big toe area. While most wide-footed runners should stick to TTS, those with a 2E width or greater may benefit from a 0.5 size increase to accommodate the upper's internal volume.
How is the arch support on the Adidas Pureboost 23?
The shoe is a neutral trainer and does not include active stability elements like medial posts. It provides a stable platform via its wide midsole base and a comfortable Ortholite insole, but its removable nature makes the shoe highly orthotic-friendly for those needing medical-grade arch support.
