Buy Izy as a plush ACG side-zip slip-on for daily walks, errands, and even light hikes; size true to size on the zipper version, size half-down on the non-zipper version that runs big, and skip it if you are buying for an elderly wearer worried about the non-locking zipper sliding down on stairs tripping hazard on steps/uneven ground for an elderly person.
Nike ACG Izy is a chunky side-zip slip-on with a plush footbed, ACG outsole, and an easy-on profile that owners cycle as a recovery shoe and a city walker. The zipper is a non-locking design, so half of owners report it stays put and half report it sliding down mid-walk my husband has them and his zipper is always sliding down just one shoe. There is also a non-zipper version that owners say runs big. Buy it for plush ACG slip-on comfort; consider the alternative ACG Rufus if zipper anxiety bothers you.
Buy true to size on the zipper version; size half a size down on the non-zipper version that runs big. Two clean data points from the reviews thread: a TTS 9.5 owner who praised the zipper version TTS for me, size 9.5, and a non-zipper owner who went down half a size and still found them a bit big I have the non zipper ones, they run big, went.5 down my next pair, still a bit big. If you split between sizes, go TTS on zipper Izy and half-down on slip-on Izy.
Mixed — half of owners report no issues, half report the zipper sliding down mid-walk because it is not a locking design. The husband-owner data point captures this clearly his zipper is always sliding down just one shoe, while another size-9.5 owner reports zero zipper issues. Buy the zipper Izy if you are willing to swap zipper pulls or accept occasional re-zipping; choose the non-zipper version or the ACG Rufus slip-on if zipper anxiety is a dealbreaker.
Yes for non-technical trails; one owner specifically reports significant hiking with them. The hiking-comfort owner directly says I've done some pretty significant hiking in them and they hold up really well, calling them super comfortable. Use them for day hikes and casual trails; choose a Mountain Fly 2 Low or a Pegasus Trail if you carry a pack or need stiffer underfoot support.
Skip the zipper version for elderly wearers worried about steps; the non-locking zipper is a tripping risk if it falls open mid-stride. The most cautionary owner advice in the reviews thread came on exactly this question could see these potentially being cumbersome or even a tripping hazard on steps/uneven ground for an elderly person. Choose the ACG Rufus full slip-on instead; the construction is similar but there is no zipper to fail.
No on both counts. Izy is an autumn/spring slip-on rather than a winter boot or a fully waterproof shoe; the asker in the reviews thread surfaced this exact question and no owner came back with a waterproof claim are they only autumn/spring shoes or are they a bit waterproof too for winter?. Buy a Gore-Tex Mountain Fly 2 Low if you need waterproof Nike ACG; treat Izy as a 3-season slip-on.
