Nike Vomero 18 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Nike Pegasus 41

Both models are built on similar Nike performance lasts. While the Pegasus 41 features a more tapered toe box and a tighter lock-down designed for faster paces, the Vomero 18 is slightly wider and more heavily padded but matches perfectly in overall linear length, allowing runners to safely maintain their standard size.

ASICS Gel-Nimbus 27

The Gel-Nimbus 27 features a highly generous, rounded toe box that easily accommodates natural toe splay. Because the Vomero 18 utilizes a tapered lateral edge that curves inward toward the pinky toe, transitioning from the Nimbus 27 requires a half-size increase to avoid lateral compression and friction against the outer toes.

ASICS Novablast 5

The Novablast 5 is known for its spacious upper and relatively roomy forefoot. Due to the heavy interior padding and full inner sleeve of the Vomero 18, which significantly compresses the foot and reduces the available internal volume, sizing up by a half-size is highly recommended to achieve a similar, unconstrained fit.

HOKA Clifton 10

The Clifton 10 is built on a straighter, foot-shaped last that is highly forgiving for different foot shapes. In contrast, the aggressively tapered shape of the Vomero 18 last requires Clifton wearers to scale up a half-size to secure adequate forefoot and toe box room.

Saucony Triumph 22

The Triumph 22 features a highly accommodating midfoot and a wider standard forefoot platform. Standard-width Triumph wearers will find the Vomero 18's standard D-width to be noticeably narrow across the metatarsals, making a half-size increase the safer choice to preserve comfortable toe spacing.
