Description
The STEPPER Spirit STS-30013 F112 are ultra-lightweight optical eyeglasses that embody Stepper’s signature philosophy of German-engineered comfort, minimalist styling, and ergonomic performance-focused design. Part of the STEPPER Spirit collection, this model is specifically designed for users who want exceptionally light everyday eyewear with a modern professional appearance and long-wear comfort.
The STS-30013 features a full-rim rectangular / softly squared silhouette with clean contemporary lines that create a balanced and versatile look suitable for both office and casual environments. The design is modern yet understated, maintaining Stepper’s “less is more” approach to eyewear aesthetics while prioritizing fit and functionality.
The “F112” color code is commonly associated with a brown or warm earthy tone, sometimes appearing as a rich translucent brown depending on lighting and production variation. This gives the frame a refined, approachable appearance with subtle vintage-inspired warmth while remaining professional and versatile.
Crafted primarily from Stepper’s proprietary TX5 material combined with stainless steel reinforcement, the frame is engineered to deliver exceptional lightness, flexibility, and durability. TX5 is known for being hypoallergenic, highly resilient, and significantly lighter than traditional acetate materials. The STS-30013 weighs approximately 7 grams, making it one of the ultra-light models in the STEPPER Spirit range.
The frame is designed with a universal comfort bridge and ergonomic skull temples, helping distribute weight evenly across the face and reducing pressure on the nose and ears during prolonged wear. Stepper eyewear is especially recognized for its comfort-first fit philosophy, making this model ideal for extended office work, reading, or continuous screen use.
The rectangular lens shape supports a wide range of lens configurations, including single vision, reading, bifocal, and progressive lenses, making the frame highly adaptable for prescription customization. The typical sizing is approximately 54 mm lens width, 16–17 mm bridge, and 140 mm temple length, placing it in a medium-fit category suitable for many adult face shapes.
