Waterproof Breathable Knee High Socks for Men - RANDY SUN

In this review of the RANDY SUN Waterproof Breathable Knee High Kayaking Hunting Fishing Socks the bottom line is simple: these are purpose-built, lightweight knee high socks for outdoor pursuits where keeping feet dry and comfortable matters. The single biggest reason to buy is the combination of a 100% PU waterproof membrane with a COOLMAX lining that aims to keep feet dry while wicking sweat during extended activity. The reviewer found them most compelling for anglers, hunters, and cold-weather hikers who want a slim, full-calf waterproof layer under boots.

Key Features

• Waterproof membrane: a lightweight 100% PU interlayer prevents external water from penetrating the sock body during wading or damp conditions.
• Breathable lining: COOLMAX fabric draws sweat away from skin to reduce clamminess and keep feet feeling drier during aerobic effort.
• Performance fit: deep heel cup and full wrap construction prevents the sock from slipping into boots and improves overall fit.
• Comfort details: smooth toe seam lowers abrasion and blister risk while an ultra-light cushion sole adds everyday comfort without bulk.
• Durable outer: nylon/polyester/elastane outer provides wear resistance and a lightweight feel for long outings.

Who It's For

These knee high socks are aimed at men who spend time in wet or cold outdoor settings: anglers crossing shallow streams, hunters moving through dewy fields, kayakers and snowboarders who want a slim waterproof barrier under footwear. The socks suit active users who prefer thin, packable waterproof protection rather than heavy neoprene overboots.

They are less appropriate for users who need a fully sealed wading system because the cuff is not waterproof and water can enter if submerged above the cuff. Also, those wanting thick thermal insulation should consider dedicated insulated socks for extreme cold.

Pros & Cons

Pros

• Lightweight waterproof membrane keeps external moisture out in many wet conditions.
• COOLMAX lining and breathable design reduce internal sweat buildup during activity.
• Comfort-focused fit with smooth toe seam and deep heel cup prevents slipping and irritation.

Cons

• Cuff is not waterproof so the socks are not suitable for full immersion above the calf.
• Some customers report mixed waterproof performance depending on use and fit, so results can vary.

Our Verdict

The RANDY SUN knee high waterproof socks are a good value for active users who need a slim, breathable waterproof layer under boots. They combine a true PU membrane with COOLMAX comfort and thoughtful fit features, making them a solid option for anglers, hunters, and trail users who avoid full submersion above the cuff. Buyers seeking full-seal waders or heavy insulation should look elsewhere.

Frequently Asked Questions

Are these truly waterproof?
They use a 100% PU membrane that blocks external water, but the cuff is not waterproof so water can enter if it goes over the top.

Can I machine wash them?
Yes, machine wash below 104 F and tumble dry below 140 F; do not iron or dry clean to preserve the membrane.

Will they keep feet warm in cold streams?
They provide thermal benefit by keeping feet dry and reducing wind chill, but they are not heavily insulated; for very cold water a thicker thermal sock or waders is recommended.
