KEEN UNEEK 360 Review 2026 | Eco-Friendly Next-Gen Hybrid Shoes Explained

Hello! This is Seki from the outdoor shop “FITTWO” in Ueno.

Today, I’d like to introduce the “UNEEK 360”, a Spring/Summer 2026 new release from KEEN.

While maintaining the original concept of the popular UNEEK series, this model has evolved beyond the boundaries of a sandal into a more shoe-like design, and is also a new eco-conscious model.

Functionality | More Than Just Looks

Excellent Fit

The upper features:

• Stretchable knit material
• UNEEK’s signature cord construction

This combination allows the shoe to naturally conform to the shape of your foot.

In addition, the bungee lace system makes it easy to adjust the fit.

The hook at the end of the lace allows you to neatly store any excess cord.

Cushioning and Lightweight Comfort

The insole uses a resilient foam material.

• A contoured structure that fits the foot
• Excellent cushioning
• Stable comfort

Furthermore, the midsole uses a lightweight injected foam material, achieving both lightweight performance and cushioning.

---

Outsole Performance

The outsole features an all-directional lug pattern.

• Excellent grip
• Slip-resistant design

In addition, it uses KEEN’s signature non-marking outsole, making it safe for indoor use as well.

---

Anti-Odor Technology

Equipped with Eco Anti-Odor (natural odor control technology).

Using naturally derived ingredients, it helps prevent odor even during extended wear.

---

Size Range

Available in 0.5 cm increments for both men’s and women’s sizes.

The men’s range goes up to 30 cm, making it suitable for those with larger feet.

---

Sustainable Design with Environmental Consideration

One of the key features of the UNEEK 360 is its eco-conscious manufacturing process.

Glue-Free Construction

Most conventional footwear uses adhesives to bond the upper and sole, but this model uses no glue at all.

Instead, the parts are secured using UNEEK’s unique cord construction.

This results in:

• Reduced environmental impact
• A structure that is easier to recycle

---

Use of Recycled Materials

The following components incorporate recycled PET materials:

• Cord system
• Upper material
• Bungee cord components
• Logo parts

While reducing the use of virgin materials, it still maintains high durability.

This is truly the most eco-friendly UNEEK ever made.
