SUBU is not just a sandal with high design appeal.
“Close to people’s daily lives”—based on this product philosophy, they pursue daily necessities as fashion, achieving a high level of functionality, design, and durability.
In this article, we will thoroughly delve into the addictive charm of why SUBU has become so popular, andexplain in detail which model suits whom. By the time you finish reading this article, you will surely be clicking “buy” on SUBU immediately.
2. Why did it become so popular? 5 “Instant Decision” charms of SUBU sandals
SUBU pioneered the winter sandal market with its superb comfort and functionality. Once you slip your feet into them, you won’t be able to go back to other sandals.
Charm 1: Unforgettable once you wear them! The ultimate “fluffy” comfort
The biggest secret of SUBU lies in its 4-layer insole. This multi-layer structure creates a level of cushioning and hold that surpasses sneakers, often described as“the feeling of carrying your home kotatsu around with you.”Specifically, it combines four layers with different functions: low-rebound urethane that gently fits the shape of your foot, high-rebound urethane that absorbs the impact of stepping and supports walking with moderate resilience, EVA material that balances lightness and cushioning, and hard EVA material that protects your feet from cold air and unevenness from the ground.
Charm 2: Wear them barefoot in winter! “Outstanding heat retention” like down
The upper (instep part) has a material feel like a down jacket. The inside is brushed, so you can feel the warmth the moment you put your feet in. Many reviews say they are warm even for those with cold sensitivity, even when worn barefoot. You will be freed from cold toes during quick winter outings or while camping.
Charm 3: Repels rain and dirt! Tough “water-repellent and stain-resistant” functionality
The standard “PERMANENT” model is treated with Teflon®, which repels some rain and dirt. The toughness that allows you to use them roughly for outdoor activities and daily use is also a charm.
Charm 4: Stress-free! “Ease of putting on and taking off” is the best
Since they are a slip-on type, you can quickly put them on and take them off at the entrance, on the veranda, or at a campsite. This stress-free usability, which is “useful in those little moments,” embodies the SUBU product philosophy of“being close to people’s daily lives.”
Charm 5: Is it really this cheap!? “Wallet-friendly” price range
Despite having this much functionality and design, the reasonable price range of around 5,000 yen per pair is also one of the charms. They are affordable compared to brand-name sandals, and many people buy multiple pairs in different colors or for different uses.
3. [Thorough Comparison] Which one suits whom? Here is the perfect SUBU for you!
Because SUBU has few models, you can choose the best pair for your lifestyle. We will introduce the main models, their features, and who they are recommended for.
First, PERMANENT(Permanent) is the standard SUBU model. It features water-repellent and stain-resistant functions due to Teflon processing, a wide variety of colors, and the most reasonable price range. It is perfect for SUBU beginners, daily use, fashion-conscious people, or those who want to try them out as indoor shoes first. If you are lost, you can't go wrong with this one.
Next, NANNEN(Nannen) is a tough model using highly flame-retardant CORDURA® 305D material. We strongly recommend it to campers, outdoor enthusiasts, and those who have bonfires, as it emphasizes durability and protection from sparks. For bonfire lovers, this is the only choice, providing peace of mind by protecting your feet from sparks.
Furthermore, AMP(Amp) is SUBU’s premium line. It uses high-quality CORDURA® material and pursues a more comfortable fit with a velvet lining. It is a 2-way specification with a removable heel belt, making it ideal for those who want to use it mainly for city wear or those seeking a higher level of comfort.
Finally, PACKBLE(Packable) is a model that uses ripstop nylon and is lightweight and foldable. It comes with a dedicated storage bag, making it useful for travel lovers, people who go on business trips often, those who want to carry them as a second pair of shoes, and for disaster prevention.
“Instant decision” model recommended for beginners: PERMANENT
For those of you who are skeptical, asking “Are SUBU really that warm?”, we recommend the standard PERMANENT first. Since you can choose from a wide variety of colors, you will definitely find a pair that matches your fashion. The price is also the most reasonable, which is the charm of being able to try them out easily.
“Instant decision” model recommended for outdoor enthusiasts: NANNEN
"My feet get cold during winter camping" or "I'm afraid of sparks from the bonfire burning holes in my shoes"—for campers with these concerns, NANNEN is the only choice. The flame-retardant material will firmly protect your feet.
4. Don't Fail at Choosing Your Size! Unisex Sizing Explained
SUBU is generally available in unisex sizes. The key to choosing the right size is "intended use" and "how you wear them".
Sizes are available in four tiers: 0 (22.0–23.5cm), 1 (24.0–25.5cm), 2 (26.0–27.5cm), and 3 (28.0–29.5cm).
• Size 0 is mainly for women (smaller) and is recommended for women who want a snug fit when wearing them barefoot.
• Size 1 is for women to men (smaller) and fits women who wear thick socks or men who want a snug fit when wearing them barefoot.
• Size 2 is the standard men's size and is recommended for the average man. If you prefer a looser fit, consider going up one size.
• Size 3 is for men (larger) and is ideal for those with wide feet or men who want an extremely loose fit.
