In fact, they are referred to as 'indoor shoes' and for good reason. Although still incredibly [cozy like a typical slipper](https://www.trendhunter.com/trends/premium-slippers) is, the Glerups Slippers boast the structure of outdoor shoes for more stability and, ultimately, more comfort. As written by the creators, this is also "due to the foot-shaped and unique design combined with the softness and warmth of the wool." Made out of [100% natural wool](https://www.trendhunter.com/trends/utility-felt-pac), the Glerups Slippers sustains, maintains and amplifies the natural heat the wearer's feet produce while also staving off moisture. Complete with either a soft calfskin or [rubber sole](https://www.trendhunter.com/trends/carhartt-wip-and-subu), it slips on effortlessly. Although modern-looking, the Glerups Slippers incorporates the long-standing tradition of Danish hand-felting. It is available in a range of colors. ## Trend Insights (Trend Hunter) - Score: 3.1/10 - Popularity: 42% | Activity: 43% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Fashion](https://www.trendhunter.com/fashion) > [Shoes](https://www.trendhunter.com/shoes) ## Key Themes ### Why This Trend Is Growing - **Indoor Outdoor Hybrids:** There is an opportunity for shoe companies to create more indoor-outdoor hybrids for increased comfort and stability. - **Natural Materials:** Sustainable and natural materials are an opportunity for footwear companies to create eco-friendly and functional products. - **Personalized Design:** There is an opportunity for companies to create personalized and unique designs for slippers, combining both tradition and modernity. ### Industries Being Reshaped - **Footwear:** The footwear industry can incorporate natural materials and traditional design while creating indoor-outdoor hybrids for increased functionality. - **Sustainability:** The sustainable fashion industry can incorporate eco-friendly and natural materials to produce more environmentally-friendly products such as slippers. - **Interior Design:** Interior design and home goods companies can create personalized slippers as part of their home decor, or include them as a complementary addition to their furniture collections. ## Related on Trend Hunter - [Ultra-Cozy Sheep Slippers](https://www.trendhunter.com/trends/sheep-slippers.md) - [Ultra-Cozy Slip-On Booties](https://www.trendhunter.com/trends/outdoor-research.md) - [Shearling-Lined Suede Slippers](https://www.trendhunter.com/trends/amour-suede-shearling-bridges.md) - [Luxe Long-Lasting House Shoes](https://www.trendhunter.com/trends/barbour-hall-quilted-slippers.md) - [Cozy Indoor Footwear Lines](https://www.trendhunter.com/trends/indoor-footwear.md) - [High-Performance Wool Boots](https://www.trendhunter.com/trends/norwegian-wool.md) - [Comfortable Home Slippers](https://www.trendhunter.com/trends/premium-slippers.md) - [Heavy-Duty Cozy Slip-On Shoes](https://www.trendhunter.com/trends/carhartt-wip-and-subu.md) - [Algae-Made Slippers](https://www.trendhunter.com/trends/vegan-slippers.md)
