Poseidon One Dive Shoe Review
The Poseidon One is a high-top, sneaker-style dive shoe intended for warm-water diving and pool use. I bought it on closeout for confined water and casual wetsuit dives, and after replacing a failed factory insole and swapping to bungee laces, it became usable and comfortable. Grip and fin compatibility are excellent, but the need for immediate modification prevents it from being a clean recommendation at full price. It is functional, but only after fixing a problem that should not exist.

- Still in my kit
- No
The Short Version
The Poseidon One works, but only after correcting a design flaw that should never have made it out the door. Once modified, it delivers good grip, easy fin fit, and reasonable comfort for warm-water and pool use. As a discounted purchase, it was worthwhile. At full price, it is hard to recommend without confirmation that the insole issue has been resolved.
Would I buy it again? Only if Poseidon has clearly fixed the insole problem in the current version.
What Works
- Strong traction on wet decks, rocks, and pool surfaces
- Fits easily in standard open-heel fins
- Comfortable and secure once modified
- Accepts simple upgrades like bungee laces
- Fun alternative to traditional neoprene boots
What Doesn't
- Factory insole failed almost immediately
- No clear communication from Poseidon on whether the issue was fixed
- Not suitable for cold water or drysuit use
- Requires modification to meet basic expectations
Why I Chose the Poseidon One Dive Shoe
I bought the Poseidon One during a closeout sale as a curiosity more than a necessity. The design stood out as a sneaker-style alternative to neoprene booties, and I wanted something different for pool work and warm-water dives.
In practice, the concept mostly worked, but the execution fell short. The factory insole disintegrated almost immediately and had to be replaced. After that fix, and after switching to bungee laces, the shoe became comfortable and functional. That said, needing to fix a brand-new product is not something I consider acceptable at full price.
Who It Makes Sense For
This item is best suited for:
- Warm-water divers looking for a sneaker-style alternative to booties
- Pool instructors or frequent confined-water users
- Divers who value grip and fin compatibility over insulation
It may not be ideal for:
- Cold-water or drysuit diving
- Anyone expecting flawless performance out of the box
- Divers unwilling to modify new gear
What It Is Like to Dive
- Fin Compatibility
- Fits standard open-heel fins with no trouble.
- Traction
- Excellent on slick decks, rocks, and poolside concrete.
- Comfort
- Great once the insole was replaced. Slightly narrow fit.
- Water Retention
- No ballooning. Drains and dries acceptably.
Ownership and Value
The outer construction held up well, but the immediate insole failure was a significant flaw. Replacing it and fitting bungee laces made the shoes easier to put on and take off. The closeout price made them worthwhile for me, but a full-price purchase would depend on confirmation that the insole problem had been fixed.
