SUNLIGHT

Foot Length: Standard
Foot Width: Standard to Slightly Narrow
Instep: Standard (Adjustable)

Model Features: Shoelace Closure
Material: Synthetic Leather / Canvas

Due to its slightly tapered silhouette toward the toe, we recommend going one size up for those with wider toes. If there is extra room in length, it can be adjusted with insoles. The shoelace design allows for fine-tuned adjustments to the fit.

AUTH

Foot Length: Standard
Foot Width: Standard to Slightly Wide
Instep: Slightly High (Adjustable)

Model Features: Cord Stopper Closure
Material: Nubuck / Synthetic Leather

Compared to shoelace styles, this model is designed with a slightly roomier fit around the instep and width. We recommend choosing a size that offers a snug, close-to-just fit. If you have a narrower foot or lower instep, consider going one size down.

MONOLITH

Foot Length: Standard
Foot Width: Standard
Instep: Standard (Adjustable)

Model Features: Velcro Strap Belt
Material: Leather

The Velcro strap across the instep allows for fine-tuned adjustments to the fit. With the updated design in this season’s model, the instep structure has been improved for greater stability. A true-to-size fit is generally recommended, but for those with a low instep, we may suggest going one size down to prevent slipping forward.

LES ARCS BOOTS

Foot Length: Standard
Foot Width: Standard
Instep: Slightly Low

Model Features: Side Gore Boots
Material: Leather

Crafted entirely from leather, this model gradually adapts to the shape of your foot over time, offering a natural and comfortable fit. Due to the side gore design, the instep area is not adjustable, and the opening and instep height are slightly lower. However, the leather will break in with wear, so we recommend choosing your true size.

THE CURVE 1 AERO

Foot Length: Standard to Slightly Long
Foot Width: Standard
Instep: Standard (Adjustable)

Model Features: Magnetic Buckle
Material: Leather / Neoprene

The magnetic buckle allows for smooth on/off, while the side straps enable adjustable fit. Designed for barefoot wear as well as with socks depending on the season or occasion. Please select the most suitable size based on your intended wearing style and environment.

SUNLIGHT CORE

Foot Length: Standard
Foot Width: Standard
Instep: Slightly Low

Model Features: Zip Closure
Material: Leather

Due to the zip construction that provides a secure hold across the instep, we recommend sizing up for those with higher insteps. Even if a larger size creates some room in the toe area, the secure fit around the instep ensures stable comfort during wear.

LES ARCS PUMPS

Foot Length: Standard
Foot Width: Standard
Instep: Slightly Low (Adjustable)

Model Features: Two level Snap Button Strap
Material: Suede

The snap button strap allows for two levels of fit adjustment. The strap length is designed for a snug fit, so we recommend sizing up for those with higher insteps.

This model is suitable for wearing barefoot as well as with socks, so please choose your size according to your wearing conditions.

THE CURVE 1

FOUNTAIN

Foot Length: Standard
Foot Width: Standard
Instep: Slightly low

Model Features: Zip type
Material: Waterproof oil leather (cowhide), waterproof nylon

The zip-up design securely wraps the instep, providing a stable fit that prevents heel slippage. For those with higher insteps, we recommend choosing one size larger.

SHELL

Foot Length: Standard
Foot Width: Standard
Instep: Slightly low (adjustable)

Model Features: Velcro tape
Material: Oil leather, nylon

Similar to the FOUNTAIN model, this design features a slightly low instep, so we recommend choosing one size larger if you have a high instep. The Velcro tape allows for fine adjustments according to foot width and instep height, making it easy to put on and take off.

See the collection

FABER

Foot Length: Standard
Foot Width: Slightly narrow
Instep: Standard (adjustable)

Model Features: Lace-up type
Material: Cow leather, polyester, nylon

Due to the slightly sharp silhouette toward the toe, we recommend choosing one size larger for those who feel pressure on their toes with narrow sneakers. If there is extra length, it can be adjusted with an insole. The shoelaces allow for fine tuning of the fit.

See the collection

SUNLIGHT VOID

Foot Length: Standard
Foot Width: Standard
Instep: Slightly low

Model Features: Slider sandals
Material: Sheepskin / Domestic linen canvas

Because the heel is open, the overall fit is slim and snug. We may recommend choosing one size larger.

See the collection

SCULP TANK

Foot Length: Standard
Foot Width: Slightly narrow
Instep: Standard

Model Features: Slider sandals
Material: Sheepskin / Domestic linen canvas

This model has a slightly narrow design. If you have wider feet, we recommend choosing one size up. For narrower feet, selecting your usual size or one size down will allow you to enjoy the comfortable fit of the leather.

See the collection

SYNC

Foot Length: Slightly long
Foot Width: Slightly wide
Instep: Standard (adjustable)

Model Features: Shoelaces
Material: Smooth leather / Synthetic fibers

The side elastic structure made with highly stretchable neoprene material provides ease of putting on and taking off, along with a high level of fit.

Because the material is genuine leather, it will gradually conform to your feet with wear, becoming even more comfortable over time.

VOGEL

Foot Length: Standard
Foot Width: Slightly narrow
Instep: Standard

Model Features: Shoelaces
Material: Waterproof cow leather / Nylon

AUTH TREK

Model Features: Shoelaces
Material: Waterproof cow leather / Pigskin

The leather gradually conforms to your foot, creating a natural fit. It may feel slightly tight at first, but comfort increases with wear. For those with wider feet, we recommend choosing a size with more room. The instep area has a bit of extra space and can be widely adjusted with the shoelaces.

See the collection

FLARE

Foot Length: Standard
Foot Width: Standard
