The Sooruz Flow 3mm Round Toe is a cross between a neoprene sock and a surf boot — thin, soft, and built for surfers who want to preserve maximum board-feel without their feet freezing. Storm Dry fleece-lined interior for warmth, GBS seams for durability, and an easy-on fit. Best for UK spring/summer/autumn surf where you want some protection but don't need the full rigid Guru 5mm winter boot.

Key features

• 3mm Limestone neoprene — thin enough to feel like a sock, warm enough to extend your shoulder-season sessions
• Storm Dry fleece-lined interior — recycled polyester, soft, warm, dries quickly between sessions
• GBS seams (Glued and Blind Stitched) — fully waterproof, durable
• Non-slip sole — strong grip on wet rocks and on your board
• Round-toe design — simpler, warmer, easier to put on than split-toe
• Easy entry — no zip, just pull on

Specification

Size chart

Sooruz boots use US shoe sizing — your UK shoe size is ONE size smaller than US (e.g. UK 9 = US 10).

Variants in this listing are labelled in US sizes (matching the boot's marking). To find your size, take your usual UK shoe size and add 1. If you're between sizes, sizing UP usually works better for boots — wetsuit boots should feel snug but not tight, and tight neoprene around the toes restricts circulation and reduces warmth. For sizing advice, call us on 01492 588001.

When to wear which thickness

• 2mm Fly Boots — UK water above 16°C (mid-summer only) or for foot protection on rocky shores where warmth isn't the issue.
• 3mm Flow — UK water 12-18°C (spring/summer/autumn). The Flow is thin and sock-like — for surfers who want maximum board-feel, not maximum warmth.
• 5mm Guru — UK water 6-12°C (autumn/winter/early spring). The standard UK cold-water boot — proper warmth, rigid foot hold, designed for serious cold-water sessions.
• 6mm Guru — UK water below 7°C (deep winter). For the coldest sessions when 5mm isn't quite enough.

About Sooruz

Sooruz is a French watersports brand founded in 1999 in La Rochelle, building wetsuits and accessories designed by riders for riders. Innovation and environmental responsibility sit at the core — Sooruz pioneered Oysterprene® neoprene (made using recycled oyster shells and bio-based components), alongside recycled fabrics, water-based glues, and circular initiatives for used wetsuits.

Sooruz makes three boot families: Flow (thin, sock-like, warmer-water surfing where board-feel matters), Guru (rigid, warm, cold-water serious-session boots in 5mm and 6mm), and Fly Boots (rocky-coast foot protection in 2mm). Each is built around the Storm Dry fleece-lined interior that customers know from Sooruz's wetsuit range.

Honest advice from us

The Flow is for surfers who want to preserve board-feel above all else — almost like wearing thick socks rather than rigid winter boots. If you're surfing in UK summer/autumn and want some warmth without losing connection to the board, this is the right pick. For colder sessions or winter use, step up to the Sooruz Guru 5mm (warmer, more rigid, proper cold-water spec). For warmer water with just rocky-shore protection in mind, look at the Fly 2mm boots. 01492 588001 for advice.
