Introducing UTIPPA, a pair of recovery room shoes born from the technology of SIDAS, an insole brand trusted by athletes around the world. This time, in collaboration with Naoko Okusa, we have created UTIPPA FUR, perfect for spending time at home during the fall and winter season.

While retaining the same function of conditioning your body from the soles of your feet, the upper is generously adorned with long-pile faux fur that makes you want to touch it. It combines a warmth that instantly puts you at ease with a glamorous style that satisfies your fashion sense.

It comes in two colors: "Smoky Rose," with a subtle sweetness, and "Ash Brown," with a calm depth.

Whether you are doing housework, working, or relaxing. This is a pair that comfortably conditions your everyday time at home from the ground up.

Available in limited quantities at AMARC LIFE STORE. In addition, customers who make a purchase will receive a free pair of SIDAS "Trail Protect [Black x White]" socks.


The Trail Protect is a comfort-focused sock featuring an asymmetrical design that takes the structure and movement of the foot into account, along with protection for the ankles, heels, and toes. The arch area features a mesh structure that increases breathability and releases sweat. It is perfect not only for everyday use but also for active days such as running and walking.

*The sock size will be included based on the size of the "UTIPPA FUR" you purchased. Please note that you cannot choose the sock size.

Adorable yet fashion-forward slippers wrapped in fluffy faux fur. They also feature SIDAS's proprietary technology to support the arch of the foot, promote blood circulation, and enable smooth movement. Design, warmth, and recovery functionality. Discover the reasons you'll want to wear them every day in these 8 points.

POINT 01
Warmth and a fashion-forward look created by rich faux fur
The upper is luxuriously adorned with long-pile faux fur. Its fluffy texture and ample volume add warmth and elegance to your feet. With a fashion-forward presence that transcends the ordinary slipper, they bring a little lift to your time at home.

POINT 02
Microfleece lining that gently wraps your feet
The inside of the upper features a microfleece lining designed for fall and winter. It gently wraps around the top of the foot, providing comfort during chilly seasons at home. Naoko Okusa selected colors that blend naturally with the faux fur on the outside. Every detail, down to the parts that touch your skin, has been carefully considered.

POINT 03
A light and airy profile created by three layered colors
The faux fur upper and two-layer sole are composed in a three-color combination. Mauve purple is paired with smoky rose, while an inky brown is paired with ash brown, with pearl white used on the bottom of both. The exquisite layering of colors creates a sporty yet sophisticated profile.

POINT 04
A unique insole shape that conditions the foot from the sole
SIDAS's unique three-dimensional shape supports the arch of the foot, which tends to sink due to fatigue. It stimulates the arch with every step, promoting blood circulation and recovery.

POINT 05
Velcro design that can be adjusted to fit your foot width and socks
The upper features a Velcro design that can be adjusted to fit your foot width. Accommodating widths from C to 3E, it flexibly fits everyone from those with wide feet and high insteps to those wearing bare feet or thick socks. By firmly holding the instep, it also brings out the unique functionality of the insole.

POINT 06
Sole design that supports smooth movement
The sole gently curves up at the toe and creates a height difference toward the heel, supporting natural movement. It is easy to walk in and makes standing up from a seated position smooth. It is designed to follow the movement of the foot to prevent slipping off while walking.

POINT 07
A deep heel cup that supports postural stability
Utilizing SIDAS's insole technology, it features a deep heel cup shape. It wraps around the heel bone and supports it in a secure position, stabilizing your posture and helping to balance your entire body from the feet up.

POINT 08
A non-slip grip sole for peace of mind at home
In response to customer feedback, the sole material has been reviewed and updated to a more slip-resistant grip sole. The fine bumps firmly grip the floor, taking care even when walking in areas prone to getting wet, such as the kitchen or around the bathroom.
