Bike Zero Cushion Ankle Socks

They are zero-cushion cycling socks designed for a close, low-profile fit in cycling shoes, minimizing bulk while maintaining foot contact with pedals.

They use a Merino wool blend (typically ~46–47% Merino wool with varying amounts of nylon, recycled nylon, and elastane) and include ZQ Merino and recycled nylon for moisture-wicking, odor resistance, temperature regulation, and softness even when wet.

They use Smartwool’s 4 Degree elite fit system for a precise, performance-oriented fit, with men's/unisex sizing and women’s-specific options available; consult the provided size chart ranges (S–XL) based on shoe size.

They’re intended for cycling—casual rides, commuting, and performance riding—and are especially well suited to warm-weather use due to their thin profile and ventilation, making them a good choice for riders who prefer a low-profile fit over extra padding.
