UGG has partnered with Nuyarn Technologies to introduce the Otzo Clog, a new lifestyle footwear offering that combines the brand’s signature comfort-driven design with advanced natural fibre performance technology.
The collaboration integrates Nuyarn’s patented wool-spinning technology into the Otzo Clog, showcasing how innovative textile engineering can enhance comfort, durability and sustainability within premium lifestyle footwear.
The Otzo Clog features a sleek nubuck upper paired with a wool jersey lining developed using Nuyarn technology. Unlike traditional ring-spun wool manufacturing methods, Nuyarn’s patented process drafts wool fibres onto a high-performance filament rather than tightly twisting them, helping preserve the fibre’s natural characteristics while significantly improving performance.
According to Nuyarn, this technology enables wool to retain its natural moisture management, breathability and thermal regulation properties while delivering enhanced strength and durability.
Commenting on the collaboration, Andy Wynne, Chief Executive Officer of Nuyarn, said:
“Pairing Nuyarn technology with iconic comfort is a perfect example of how our technology can elevate a lifestyle product into a high-performance essential. We are thrilled to see Nuyarn applied to a globally recognised brand like UGG. Our goal has always been to prove that natural fibres can outperform synthetics when engineered correctly.”
Monica Ebert, Vice President of Sales at Nuyarn, added:
“Partnering with UGG allows us to take the natural performance benefits of wool; breathability, warmth, and moisture management and amplify them through a technology that reflects our commitment to innovation and premium quality.”
Performance Benefits of Nuyarn Technology
The Otzo Clog incorporates Responsible Wool Standard (RWS)-certified wool and leverages Nuyarn’s advanced spinning technology to deliver several performance enhancements, including:
- Up to 8.8 times greater durability compared to conventional wool.
- Drying speeds up to five times faster than traditional ring-spun wool.
- Approximately 35% higher thermal retention for improved temperature regulation.
- Up to 85% greater elasticity and 50% higher burst strength without the use of spandex.
Supporting Sustainable Innovation
The partnership also reflects growing demand for renewable and natural materials within the fashion and footwear industries. According to Nuyarn, its manufacturing process requires 30% fewer raw materials and consumes 73% less energy compared to conventional wool spinning methods.
The use of RWS-certified wool further supports responsible sourcing practices by ensuring compliance with animal welfare and sustainable land management standards throughout the supply chain.
By combining advanced textile engineering with natural fibre performance, the UGG Otzo Clog demonstrates how innovation can enhance both functionality and sustainability in modern footwear design, while reinforcing the growing role of high-performance natural materials within the global fashion industry.
