Full breakdown

Nike Calm Slide is the brand’s firm-foam sport slide — a single-piece molded body with a contoured footbed and the Nike branding embossed on the strap. The original 1.0 is openly divisive: one r/Nike thread titled the slides-of-2026 review calls the originals one of the most uncomfortable slides the reviewer had ever felt, like walking on concrete, before pivoting to praise the much softer 2.0 revamp the original Calms were probably the most uncomfortable slides I’ve ever felt, like walking on concrete. Buy the Calm 2.0 for a soft recovery-style slide; pass on the 1.0 unless you actually want a firm, supportive footbed.

FAQ

Should I buy the Calm Slide 1.0 or wait for the Calm Slide 2.0?

Buy the 2.0 over the 1.0 in most cases — the 2.0 is genuinely a different shoe, not just a colorway refresh. The r/Nike Calm 2.0 review thread says the 2.0 is so much softer that it makes the ReactX slides feel hard and the original 1.0 feel like concrete they make the ReactX slides feel hard... I’ve never felt foam this soft, and a follow-up buyer specifically regrets buying the 1.0 first I got the first version and I hated how hard they are... wish I would have waited. Only choose the 1.0 if you specifically want a firm, supportive footbed.

Is the original Calm Slide actually uncomfortable, or just firm?

It is firm-supportive, and whether you call that comfortable depends on your foot and your use case. One r/Nike owner who does a lot of walking for work says the 1.0 firmness is perfect for them because it stabilizes the foot the firmness of the slide stabilizes my feet, while another buyer compares them to walking on concrete and dismisses the comfort claim outright like walking on concrete. There is also a real bottom-of-heel pain report on the 1.0 after weeks of wear just started getting heel pain on like the bottom, so if your feet need plush foam to feel good, do not buy a Calm 1.0.

How does the Calm Slide compare to the Nike ReactX Rejuven8?

The Calm 1.0 is firmer than the Rejuven8; the Calm 2.0 is comparable to or softer than the Rejuven8. The Calm 2.0 review thread argues directly that it is not a stretch to say the Calm 2.0 is better than the Rejuven8 in terms of comfort its not a stretch to say its better than the RJVN8, and a cross-shop thread from a university buyer choosing between the two confirms both are well-rated but with different feels the Calm 1.0 are more firm than both but honestly I love them... the 2.0 are softer and comparable in general feel to the Rejuven8. Pick by the feel you want: firm-supportive Calm 1.0, soft Calm 2.0, or soft cushioned Rejuven8.

How should I size the Nike Calm Slide?

Many owners go a half size up because Calm Slides run only in whole sizes and the next size down can feel too tight. A 1.0 buyer between an 8.5 and an 8 says the 7 felt right but the 8 left heel space at the back and they wanted a 7.5 that doesn’t exist tried on a 7 and 8... felt like I would need a 7.5 which doesn’t exist. If your foot is narrow, size down; if it is wide or you wear them with socks, size up. Try in store before any final-sale color if you are between sizes.

Do Calm Slides hold up to hot cars and outdoor wear?

No — Calm Slide foam shrinks in hot cars, which is a known Nike sandal-line failure mode rather than a fluke. One r/Nike owner had to buy a second pair after leaving the first in a hot car and watching them shrink don’t leave them in a hot car because they’ll shrink. Had to buy a second pair after that, with a follow-up commenter calling out the same issue on a different older Nike sandal they shrink so much that I can’t even wear them anymore. I guess they haven’t changed the material at all. Keep them out of direct sun and the trunk, and treat them as house/short-walk slides rather than long outdoor walkers.
