Reef Size Guide: How to Find Your Perfect Fit & What to Buy

Looking for the perfect pair of Reef sandals or casual shoes but unsure what size to order? You’re not alone. Known for their relaxed coastal vibe and beach-friendly designs, Reef is a go-to for summer-ready footwear—but like many global brands, sizing can vary across regions and styles.

At Tellar.co.uk, we specialise in helping you find your perfect size in over 1,500 brands, including Reef. Whether you're shopping flip-flops, slides, or clothing from their surf-inspired line, this guide will walk you through how Reef fits, what to buy, and how Tellar can help you shop smarter.

Who Are Reef?

Founded in 1984 by two Argentine brothers, Reef is synonymous with premium sandals, environmentally friendly production, and surf culture style. While best known for their comfortable flip-flops, Reef also offers:

Beach-ready sliders and casual trainers
Activewear and loungewear for men and women
Sustainable footwear using recycled materials

Reef products combine laid-back aesthetics with technical comfort. But depending on where you shop—UK, US, or EU—size charts and fits can vary, which is where Tellar steps in.

Does Reef Run Big or Small?

Reef is known for running true to size in men's sandals, but women’s and kids' sizes can be inconsistent depending on style. Some customers report:

Flip-flops fit narrow, especially for high arches
Sliders are roomier, ideal for wider feet
Trainers and shoes tend to run slightly large

Still, Reef’s sizing depends on foot shape, arch height, and region of manufacture—which is why trying to guess your size can lead to returns and frustration.

Instead of guessing, use Tellar’s free sizing tool to match your body measurements to Reef’s size system with data-driven accuracy.

Regional Sizing: UK vs US vs EU in Reef Footwear

Like many American brands, Reef sizes are originally based on US sizing, which can cause confusion for UK and EU shoppers. Here’s a general conversion:

US Size	UK Size	EU Size
6	5	38
7	6	39
8	7	40.5
9	8	42
10	9	43

🟢 But for personalised accuracy, always use Tellar’s size match tool instead of relying on conversion tables. Our database accounts for style-specific fit notes from real customer feedback.

What to Watch Out For

Even with the right size, some users struggle with:

Tight straps on first wear (especially leather)
Loose heel support in some flip-flop designs
Limited half-sizes in certain product lines

Tellar.co.uk provides alerts for these issues and advises when to size up, down, or switch styles.
