Nike Air Monarch IV Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Nike Air Force 1

The Nike Air Force 1 is built on an exceptionally spacious last with an open, wide toe box. In direct contrast, the Air Monarch IV features thick internal padding and a heavily tapered toe box layout. To achieve the same relative toe box freedom and match the internal room of the AF1, buyers must size up by a half-size.

New Balance 608 (v5)

The New Balance 608v5 is a direct competitor that offers a more natural, less restrictive standard D-width fit footprint. Wearers switching to the standard-width Air Monarch IV will experience an overly tight midfoot and ball-of-foot compression. Moving up a half-size or transitioning directly to Nike's 4E extra-wide width configuration is essential to maintain proper horizontal clearance.

Nike Dunk Low

The Nike Dunk Low features a flatter, lower-profile upper with minimal internal padding. The heavy, multi-layered leather panels and thick, plush tongue of the Air Monarch IV significantly compress the upper forefoot chamber. Selecting a half-size larger than your standard Dunk size prevents localized pressure points and toe crowding.

Adidas Samba

The Adidas Samba utilizes a notably flat, narrow, low-volume indoor soccer last where users often size up a half-size strictly to gain lateral width rather than length. The Air Monarch IV provides much more generous underfoot cushioning, but its thick interior padding creates a short-fitting toe box. If you already size up in the Samba for lateral relief, you should maintain that 10.5 size in the Monarch IV to guarantee proper length without creating a logical contradiction in fit parameters.
