Nike | Women’s Infinity RN 4 Road Running Shoes – Black/Hyper Violet

Advice for Road Runners: The Nike Women’s Infinity RN 4 Running Shoes offer great cushioning and support. These are best suited to runners who have some instability in their feet and ankles.

Underfoot Feel

ReactX foam should feel protective, yet responsive underfoot. The combination of this foam and the curved heel-to-toe design should result in an energetic underfoot experience. By this, we mean it should feel easier to maintain your pace and momentum in the Nike Infinity RN 4 Running Shoes.

Tuned support and intentionally placed cushioning work in harmony to stabilise your feet and ankles. This type of support should also feel natural if you have imbalances between your left and right side.

Upper Fit

The Nike Infinity RN 4 Running Shoes feature a supportive Flyknit upper. With an internal Flyknit fit band in the midfoot, and a spacious forefoot design, your feet should feel like they have the best of both worlds. 

However, we need to note, Nike acknowledged that these have a snug fit. We recommend ordering a half-size up from your normal Nike running shoes.

Finally, the Infinity RN 4 has a water-repellent liner in the front of the toe box. This helps to keep your toes drier in wet weather conditions.

Ideal Run Type

The Nike Women’s Infinity RN 4 Running Shoes should offer a dynamic underfoot experience. Meaning they’re likely to feel comfortable for both slower and steady paced runs. A great benefit for runners who vary their effort levels from day to day.

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.
