The SI-87066 typically features a full-rim rectangular to softly squared silhouette, offering a versatile and contemporary look suitable for both business and casual environments. The shape is designed to provide balanced facial proportions while supporting a wide range of prescription lens types.

Stepper frames in the SI-87000 series are commonly associated with lightweight titanium or TX5 hybrid material construction, engineered to minimize pressure on the nose and ears during long periods of wear. This makes the frame especially suitable for users who prioritize comfort and durability over heavy fashion styling.

Build & Materials

The SI-87066 is generally constructed using:

• Titanium or Stepper TX5 lightweight material
• Hypoallergenic frame components
• Corrosion-resistant structure
• Flexible and durable engineering for daily wear

Stepper’s TX5 and titanium systems are specifically designed to create frames that feel nearly weightless while still maintaining structural strength and flexibility.

Design & Comfort Features

The SI-87066 follows Stepper’s ergonomic design philosophy:

• Full-rim rectangular / soft-square frame structure
• Lightweight temples designed to reduce pressure behind the ears
• Adjustable or ergonomic bridge support for balanced fit
• Flexible hinge system in many variants for improved durability
• Stable frame geometry for long-term prescription use

These features make the frame particularly comfortable for office work, reading, driving, and extended screen use.

Fit & Sizing

Although exact measurements can vary depending on production variation, SI-series Stepper frames of this category are commonly sized around:

• Lens width: 53–56 mm
• Bridge width: 16–18 mm
• Temple length: 140 mm

This places the SI-87066 in a medium fit category, suitable for most adult face shapes.

Lens Compatibility

The frame supports:

• Single vision lenses
• Reading lenses
• Bifocal lenses
• Progressive lenses

The rectangular geometry is especially compatible with progressive lens setups due to its stable lens height and balanced proportions.
