These flat knit crew socks combine 21s polyester and 32s/4 polyester using a changing lanes / merging construction. The 144-needle knitting creates a clean, smooth sock surface with a non-cushioned foot structure designed to reduce unnecessary bulk inside footwear.
This model is differentiated from similar products in the collection by its extended size 9–14 construction, making it suitable for private label programs that require a broader adult size range. The 21s polyester and 32s/4 polyester combination provides brands with a distinctive dual-yarn construction while maintaining a streamlined everyday crew sock profile.
The flat, non-cushioned design works well for daily wear, commuting, casual footwear, uniform programs, travel collections, and basic lifestyle sock ranges.
