Product Information
The Bare 5mm Neoprene Ultrawarmth Drysuit Diving Boots are 5mm thermal dive boots lined with low-loft OMNIRED infrared inner fabric, built with a heavy-duty zippered entry and double-glued, blindstitched seams. They are made to restrict water flow, protect feet from sharp objects, and prevent fin blistering, and are offered in black in sizes 05 to 13.
Who it is for
These boots suit scuba divers who want extra foot warmth in cool and cold water, whether the dive is from a boat, a beach, or a rocky shore entry. The heavy-duty sole adds stability on rocky or uneven terrain, and the toe and heel caps plus the fin tab help divers who log long days in fins. The zippered entry with a wide gusset makes them practical for divers who need to get boots on and off quickly between dives.
Key details
- Core: 5mm neoprene with a low-loft OMNIRED infrared inner fabric that converts body heat into infrared energy.
- Flex panels: ELASTEK full-stretch neoprene around the ankles and upper calves, with fused cut edges for unrestricted stretch.
- Construction: Double-glued and blindstitched seams.
- Entry: Heavy-duty zipper with a wide gusset.
- Protection: Durable toe and heel cap, fin tab to prevent strap movement, heavy-duty sole.
- Color and MPN root: Black, Bare SKU 044921.
Compatibility and sizing
DiveCatalog carries sizes 05, 06, 07, 08, 09, 10, 11, 12 and 13. Bare also publishes a size 04 in this model. Because 5mm neoprene adds bulk around the foot, check that your fins leave room for the boot before you dive.

Frequently Asked Questions
What sizes do the Bare 5mm Ultrawarmth boots come in?
DiveCatalog lists sizes 05, 06, 07, 08, 09, 10, 11, 12 and 13 in black. Bare also publishes a size 04 for this model. Each size has its own SKU built on the 044921BLK root, for example 044921BLK-0305 for size 05. If you are between sizes or unsure how the boot fits with your fins, call 888-701-4017 and we will help.
What is OMNIRED infrared technology in these boots?
OMNIRED is the low-loft infrared inner fabric Bare builds into the Ultrawarmth boot. It converts the wearer's body heat into infrared energy, and Bare states the technology is FDA-determined to conserve body heat and accelerate thermal recovery. It sits against the foot inside the 5mm neoprene core, so you get the thermal benefit without adding bulky loft inside the boot.
How do you get these boots on and off?
The Ultrawarmth boot uses a heavy-duty zipper with a wide gusset, so the opening spreads wide for easy entry and exit. ELASTEK full-stretch neoprene at the ankle and upper calf plus fused cut edges let the boot stretch without restriction, which also helps when pulling them on with cold hands.
Will the 5mm thickness affect my fin fit?
It can. The boot uses 5mm neoprene with a heavy-duty sole and toe and heel caps, so confirm your fin foot pocket has room before diving. The boot includes a fin tab that keeps the fin strap from sliding up or down once the fin is on. Contact us at 888-701-4017 if you want help checking fit.
