The private brand KACHIKA, developed by SynaBiz Inc., has released new rain shoes just in time for the rainy season. The shoes are designed to provide waterproof performance while maintaining a minimal look and a fit similar to everyday sneakers.
Beyond the "Obviously Rain Boots" Look
Choosing rainy day footwear often involves a trade-off: prioritizing waterproofing tends to limit design options, while prioritizing style can leave doubts about durability and ease of walking.
KACHIKA's new rain shoes were developed to address these everyday frustrations. The design is minimal and the fit is light, much like a pair of sneakers. The shoes are styled to look natural on sunny days as well as rainy ones, making them a versatile option for daily use.
Key Features
1. Soft, Bouncy Fit for All-Day Comfort
The flexible waterproof material moves with the foot for a snug, comfortable fit. The design addresses a common issue with traditional rain shoes — ankle chafing from stiff rubber — aiming for a gentler wearing experience.
An original KACHIKA cushioned insole is also included, supporting a light, sneaker-like stride even on wet days.

2. Odor Reduction Throughout the Day
A built-in space called the "Deodorant Room" is incorporated into the shoe interior. Since rain shoes tend to trap air inside their sealed structure, this feature absorbs and neutralizes odor-causing substances such as ammonia, acetic acid, and isovaleric acid — helping to reduce discomfort even after extended wear.

3. Grip on Wet Tiles and Snowy Roads
The sole features a high-performance anti-slip design suited for both rainy and snowy conditions. A special wave-shaped pattern channels water away from the contact surface, providing grip on wet tiles and slippery roads.
With its minimal styling that avoids the look of traditional rubber boots, the shoes suit a wide range of everyday settings — commuting, school, shopping, and more.
