Nike Pegasus 41 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Nike Air Force 1

The Nike Air Force 1 is a classic lifestyle shoe built on a spacious, retro last that typically runs a half-size larger than standard athletic running footwear. Transitioning to the narrow, highly structured MR-10 last of the Pegasus 41 requires sizing up by a half-size to achieve a comparable fit and prevent severe forefoot compression, balancing the generous lifestyle width with the tight performance fit of the Pegasus.

Brooks Ghost 16 / 17

Both daily trainers run true to size in length. However, the Brooks Ghost features a significantly wider, more rounded toe box allowing natural toe splay. Runners with average to narrow feet can maintain their exact size, but those utilizing the full width of a standard Brooks Ghost will find the standard D-width Pegasus 41 excessively snug and should opt for the Nike Wide or Extra Wide variant instead of trying to compensate by adding unnecessary linear length.

Hoka Clifton 9

Both shoes utilize performance-oriented lasts that run slightly narrow, making length and width sizing highly consistent between the two models. Runners can safely maintain their true size across both, though the Clifton 9 offers a slightly wider midfoot base that is inherently more forgiving for runners sensitive to arch pressure compared to the tight internal midfoot band of the Pegasus 41.

Saucony Ride 18

The Saucony Ride 18 is designed with a broader anatomical forefoot and a more accommodating midfoot wrap. Runners who prefer the relaxed feel of the Ride 18 will feel restricted by the tight, tapered toe box of the Pegasus 41. To replicate the comfort of the Saucony without sacrificing security, sizing up by a half-size or transitioning to the Nike Extra Wide (4E) option is strongly advised to properly scale width without creating heel slippage.
