Nike ReactX Rejuven8 Size Chart India: Adult and Grade School Sizing
Nike ReactX Rejuven8 Shoes & Slides Size Chart
Sizes are processed in US sizing on Nike. There may be slight variations between styles and collections, and the Rejuven8's one piece foam build has no laces or straps to adjust the fit after the fact. If you're between sizes, consider the next half size up.
The Rejuven8 is Nike's slip on comfort shoe built with ReactX foam, meant for recovery days, travel, and everyday wear rather than performance running. Because there's no lacing system to tighten a loose fit, getting the size right the first time matters more here than on a regular sneaker. Buyers picking up the Nike Reactx Rejuven8 Medium Olive or the Nike Reactx Rejuven8 Triple Black should treat the chart below as the starting point, then check the stock note underneath for what's actually available to order today.

Nike lists the Rejuven8 in unisex sizing off the men's scale above. Women shopping the same colourway typically drop about one and a half UK sizes from their regular women's size to land on the matching men's number, the same offset Nike applies across its ReactX and comfort lineup.

What Kicks Machine actually stocks right now
The brand's own range runs wider than what's live at checkout, so here's the real, buyable picture as of this page's publish date. Adult unisex pairs such as the Nike Reactx Rejuven8 Light Orewood Brown currently ship in UK 4.5 through UK 14. Nike's official chart above only publishes conversions through UK 12, so UK 13 and UK 14 are genuine Kicks Machine stock but don't have a published CM or EU equivalent from Nike, if you wear a UK 13 or 14 in other Nike shoes this size should match, but message the team before ordering if you're unsure. On the GS side, the Nike Reactx Rejuven8 Elemental Pink (Gs) and the Nike Reactx Rejuven8 Triple Black (Gs) both run UK 1.5 through UK 6, covering the full GS table above. Every pair goes through Kicks Machine's in house authentication check before it ships, so getting the size guidance right here is the main thing standing between a comfortable pair and a return.
Frequently Asked Questions
Does the Nike ReactX Rejuven8 run true to size?
Yes, most buyers order their regular Nike size. It runs generously enough that narrow feet may prefer half a size down, while wide feet tend to find it accommodating as is. Since there's no lace or strap to adjust afterward, stick with your usual size unless you have a specific reason to size down, and check the [Nike Reactx Rejuven8 Medium Olive](https://www.kicksmachine.com/products/nike-reactx-rejuven8-medium-olive-sale) listing for the exact UK options in stock.What is the largest size Kicks Machine stocks in the Rejuven8?
UK 14 is the largest adult size currently live, seen on colourways like the [Nike Reactx Rejuven8 Triple Black](https://www.kicksmachine.com/products/nike-reactx-rejuven8-triple-black-sale). Sizes above UK 12 aren't part of Nike's officially published conversion table, so treat UK 13 and 14 as matching your usual Nike size rather than assuming an exact CM figure.How does GS sizing on the Rejuven8 differ from adult sizing?
GS (grade school) sizing uses Nike's youth scale, which is a separate numbering system, not a smaller version of the adult chart. A GS UK 6, for example, lines up with an adult UK 6 by coincidence at the top of the youth range, but everything below that point runs on its own scale. Check the size table on the [Nike Reactx Rejuven8 Elemental Pink (Gs)](https://www.kicksmachine.com/products/nike-reactx-rejuven8-elemental-pink-gs-sale) page before ordering for a child.Can I exchange a Rejuven8 if the size feels off after wearing it once?
Kicks Machine's return and exchange policy covers unworn pairs in original packaging, so it's worth trying the shoe on a clean, dry surface indoors before stepping outside in it. Since the foam construction has no adjustability, confirming fit early matters more here than with a laced sneaker.Is the Rejuven8 sized the same across every colourway?
Yes, the sizing scale is consistent across colourways within the same GS or adult category. What changes between listings such as the [Nike Reactx Rejuven8 Triple Black (Gs)](https://www.kicksmachine.com/products/nike-reactx-rejuven8-triple-black-gs-sale) and other GS colourways is stock availability at each size, not the size scale itself, so always check the live variant list on the specific product page rather than assuming a size open on one colourway is open on all of them.Once you've settled on a size, browse the full Nike ReactX Rejuven8 collection for every colourway currently in stock, from adult neutrals to GS pairs for younger feet. Every pair ships with Kicks Machine's authentication check and cash on delivery across India, so sizing right the first time is the only thing left to get right.
