Nike | Men’s InfinityRN 4 Blueprint Road Running Shoes

Advice for Road Runners: The Nike Men’s InfinityRN 4 Blueprint Road Running Shoes are a great option for runners seeking cushioning and some added stability.

This colourway is part of the Nike Blueprint Pack. The Blueprint colourway is inspired by Nike’s co-founder, Bill Bowerman, who – in the words of Nike – created “the blueprint for serving athletes”.

Underfoot Feel

The midsole is made of Nike’s ReactX foam. This responsive foam provides a lot of underfoot cushioning, but it does not feel overly soft. Tuned support and intentionally placed cushioning provides extra stability for your feet and ankles. The InfinityRN 4 should provide a very stable platform from which to land and push off from.

A rockered heel-to-toe design should help you to move through the gait cycle with greater ease and efficiency. Finally, Nike’s Waffle outsole provides durable traction.

Upper Fit

The upper has sock-like fit. The fabric is supportive, but it feels very soft. It is definitely worth highlighting that the upper has a snug fit. Nike acknowledged that these have a snug fit. We recommend ordering a half-size up from your normal Nike running shoes.

The Nike InfinityRN 4 offers a wider toe box so that your feet can splay naturally. We should point out that part of the toe box has a water-repellent liner – helping to keep your feet drier in wet weather.

Ideal Run Type

The Nike Men’s InfinityRN 4 Blueprint Road Running Shoes are well suited to lower intensity running. There is a lot of cushioning in the midsole, therefore, they should feel comfortable on long-distance runs.

Sizing Advice

Shoe size is a personal preference and everyone’s feet are different, but we want to ensure you avoid any pain or discomfort from bruised toenails, rubbing, blistering or pins and needles.

Your running shoes should have enough width to allow you to spread your toes and should have some space at the front (we recommend having a half to one thumb’s width of space from the end of your longest toe to the front of your running shoes).

This usually means that your running shoe will be at least a half size bigger than your regular shoe size though this can vary from brand to brand.
