Heatlock® finished-sock platform
Thermal comfort, engineered from yarn to sock.
Heatlock® aerogel far-infrared wool-blend thermal socks bring three material roles into one configurable platform: insulation-focused aerogel polyester, FIR-focused polyester and wool-blend comfort.
Developed for outdoor, sports, travel and wellness-inspired collections, the current sample range includes black and white crew and ankle styles. Fiber ratio, yarn count, cushioning, knit structure and branding can be adjusted around the buyer’s product brief.
The material system
Three components, three distinct jobs
The yarn is designed as a complementary system. The finished result depends on the selected blend, sock construction, footwear and use conditions—not on any single fiber in isolation.
Aerogel polyester
An insulation-focused component selected to support lightweight thermal-comfort constructions.
Far-infrared polyester
Provides the material basis for FIR-focused warmth and comfort positioning, subject to the required test method.
Wool blend
Contributes softness, moisture buffering and familiar cold-weather comfort within the chosen blend.
Current sample range
Four starting points for development
Choose the closest format, then refine yarn, cushioning, support zones, sizing and branding for the intended collection.
Outdoor coverage
A practical base for hiking, cold-weather running and outdoor training concepts.
Training profile
A lower-cut direction for gym, running and everyday performance footwear.
Visible technical style
Suitable as a starting point for winter travel, outdoor and thermal lifestyle ranges.
Wellness-led comfort
A clean, low-cut format for mobility, studio and recovery-inspired comfort collections.
Application direction
Match the construction to the moment of use
A thermal sock performs as part of a system. Activity level, climate, footwear fit and moisture load should shape the development brief.
- Cold-weather activityHiking, trail use, skiing and outdoor training concepts where warmth and footwear compatibility matter.
- Travel and everyday wearComfort-focused socks for cooler journeys, commuting and seasonal lifestyle ranges.
- Post-activity comfortRecovery-inspired positioning for rest, mobility and wellness collections—without an unverified medical or recovery claim.
Project configuration
Specify the sock your market needs
The four samples are development references rather than a fixed one-spec product. Final feasibility, MOQ and lead time are confirmed against the selected construction.
- Length and fit
- Crew or ankle, with target size range and fit profile.
- Yarn construction
- Fiber ratio, yarn count and wool grade can be reviewed by project.
- Cushioning zones
- Heel, toe and sole cushioning can be adjusted for the intended footwear.
- Knit engineering
- Arch support, ventilation, rib structure and density can be developed to brief.
- Color direction
- Black and white samples are available; project colors require feasibility confirmation.
- Brand presentation
- Knitted Heatlock® branding, private label, packaging and size marking can be discussed.
Turn one of these four styles into your own sock specification.
Send the target length, size range, climate, footwear type, cushioning zones, color, branding, test method and forecast quantity. We will use them to prepare the next development discussion.
