Short answer
The ASICS GEL-Nimbus 27 sets a benchmark in high-cushion performance, delivering an exceptionally comfortable daily training option that fits true to size (TTS) in linear length. Featuring a redesigned single-layer engineered jacquard mesh upper, the model provides a snug, structurally locked midfoot fit that eliminates heel slippage entirely.

Fit Notes
- ASICS GEL-Nimbus 26
- The GEL-Nimbus 27 offers a wider, less tapered toe box and deeper vertical depth in the forefoot compared to the shallower, narrower profile of the Nimbus 26. Standard-to-narrow feet will experience a more accommodating fit in the exact same size. However, because the single-layer jacquard mesh on the 27 is lighter and less restrictive than the 26's thick knit, runners with highly shallow feet might feel the upper is slightly loose and need to utilize a runner's knot to prevent midfoot shifting.
- New Balance Fresh Foam X 1080 v14
- The New Balance 1080 v14 features a snugger midfoot wrap and a stiffer, lower-volume toe box cover that frequently presses down on the toes. While both models run true to length, the GEL-Nimbus 27 provides significantly more horizontal room and freedom in the forefoot. Runners who historically sized up a half-size in the New Balance solely as a compensation factor to alleviate vertical toe pressure should return to their true standard length (TTS) in the GEL-Nimbus 27.
- Brooks Glycerin Max
- Both models fit true to size regarding linear length. However, the Glycerin Max lacks alternative width configurations and has a strictly moderate toe box width. The GEL-Nimbus 27 provides a wider forefoot platform and offers standard, wide, and extra-wide options. Wide-footed runners do not need to size up in length to find lateral relief; they can confidently select their true length size in an expanded ASICS width SKU.
- Hoka Clifton 10
- The Clifton 10 provides generous vertical volume over the instep with a highly accommodating upper architecture. Conversely, the GEL-Nimbus 27 features a lower vertical clearance across the top of the foot and a more tapered standard ceiling. Runners with average feet can stick true to size, but those with exceptionally high insteps or high-volume feet may find the top of the Nimbus 27 too tight, necessitating either a half-size increase or transitioning to a dedicated wide version to gain vertical space.
Sizing FAQ
Does the ASICS GEL-Nimbus 27 run true to size?
Yes, the ASICS GEL-Nimbus 27 runs true to size in terms of linear length based on comprehensive tracking data and laboratory measurements. Ordering your standard running shoe size provides an accurate fit with ample room at the front to prevent toe bruising over high mileages. While the vertical clearance directly over the toes and instep is relatively low-volume, the structured engineered jacquard mesh upper will adapt, stretch, and mold specifically to the contours of your foot after a brief break-in period of 10 to 15 miles.
Is the ASICS GEL-Nimbus 27 good for wide feet?
The ASICS GEL-Nimbus 27 is highly suitable for wide feet due to an updated, wider, and less tapered toe box geometry compared to previous iterations. The forefoot platform measures approximately 98.4 mm at its widest point, providing excellent lateral space for natural toe splay and unavoidable foot swelling during long endurance efforts. Furthermore, ASICS offers comprehensive wide and extra-wide selections—Standard (D), Wide (2E), and Extra-Wide (4E) for men; Narrow (A), Standard (B), and Wide (D) for women—ensuring wide-footed individuals can achieve an anatomically correct fit without having to size up in length.
How is the arch support on the ASICS GEL-Nimbus 27?
Because the ASICS GEL-Nimbus 27 is classified as a neutral running shoe, it does not feature aggressive or rigid medial arch posts. Instead, it relies on exceptional inherent stability built directly into the midsole geometry. The footprint of the FF BLAST PLUS ECO foam is remarkably broad through the heel and forefoot to counteract lateral rolling, while the foam sidewalls wrap upward to cradle and center the heel during impact. This layout provides dependable, non-intrusive support for neutral runners, mild underpronators, and mild overpronators, while its deep heel pocket easily accommodates custom orthotics.
