Adidas Solarglide 5 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Nike Pegasus 40/41

Nike's Pegasus utilizes a narrower last compared to the voluminous Solarglide 5. While the internal length is nearly identical, the Solarglide 5 offers a significantly roomier midfoot and forefoot volume. If the Pegasus fits you perfectly in length, stay with your standard size in the Solarglide 5 but expect a much wider platform and less compressive feel.

Nike Air Force 1

The Nike Air Force 1 is notorious for running approximately a half-size large. Because the Solarglide 5 is a performance trainer with a more accurate linear length, you must return to your true performance size. Sizing up by 0.5 from your 'shrunken' AF1 size is essential to ensure adequate toe room for running.

Adidas Samba OG

The Samba is a very narrow, low-profile shoe. If you typically size up in the Samba just to achieve more width, you should return to your true length for the Solarglide 5. The Solarglide's naturally wide base and flared midsole will comfortably accommodate your foot width without the need for additional length compensation.

Brooks Ghost 15/16

Both shoes target the high-mileage trainer category with accommodating fits. The linear length is nearly identical, though the Solarglide 5 will feel stiffer initially due to the LEP 2.0 system. Stick with your standard Brooks size, but be prepared for a longer break-in period to reach the same level of flexibility.
