Quick specs

Type: Round toe surf boot
Thickness: 5 mm
Interior: Thermo Dry Inferno (TDI)
Exterior: Channel Flex
Cuff: Drylock cuff opening to limit flushing
Straps: Ergonomic instep strap plus heel strap for pull-on

Xcel describes the current Drylock boot as updated with a sleeker design and reduced bulk, contoured to the foot while minimising rubber under the sole. The listing credits the Thermo Dry Inferno interior and Channel Flex exterior for warmth, with the Drylock cuff preventing flushing.

The ergonomic strap is described as keeping the heel locked in and taking pressure off the instep, and a separate heel strap is included to make the boot easier to pull on.

Cleanline Surf stocks a 2024 black and grey version of the same 5mm round toe boot at $79.96, described with Celliant Black lining rather than the current TDI interior. Treat the two as different production years rather than the same product.

Pros & cons

Thermo Dry Inferno interior and Channel Flex exterior are the warmest combination in the Xcel boot line
Drylock cuff is designed to stop water pumping in at the ankle
Reduced sole rubber keeps board feel closer to a thinner boot
Half sizes at 9.5 and 10.5 help riders between full sizes

A 5 mm round toe is bulkier underfoot than 3 mm split toe options
Discounted stock is usually the older colourway rather than the current black
Published customer ratings come from small review counts, so read them as indicative only

How it surfs

Ratings are published in two places. SwimOutlet lists 4.4 out of 5 from five reviews and Wetsuit Wearhouse lists 5 out of 5 from four reviews, which convert to 8.8 and 10 on the ten point scale used across this site.

Price varies more than specification. The Xcel store and Wetsuit Wearhouse both list $104.95 for the current black boot, while SwimOutlet and Cleanline sell earlier colourways at $74.96 and $79.96.

For thickness and fit decisions before buying, the surf booties guide covers temperature bands and toe styles, and cold water suit pairings are covered in the Xcel Drylock 5/4 hooded review and the wider wetsuit reviews index.

Frequently asked questions

How warm is the Xcel Drylock 5mm boot?+

It is the 5 mm option in the Xcel range, built with a Thermo Dry Inferno interior, Channel Flex exterior and a Drylock cuff that the brand states prevents flushing. Xcel does not publish a temperature range for the boot itself.

What does the Drylock cuff do?+

Xcel describes the cuff opening as preventing flushing, meaning it limits cold water pumping in and out around the ankle during a session.

How much does it cost?+

$104.95 on the Xcel store and at Wetsuit Wearhouse. Earlier colourways were listed at $79.96 at Cleanline Surf and $74.96 at SwimOutlet when checked.

What sizes does it come in?+

US 5 through 13, including half sizes at 9.5 and 10.5.

Round toe or split toe?+

This model is round toe. Round toe boots keep the foot warmer as a single chamber, while split toe versions trade some warmth for board feel. The booties guide explains the difference in more detail.
