Can the socks provide better compression to help reduce muscle soreness?
Junhao Lo –
Dear Emily, thank you for choosing our Mares Flex 20 Ultrastretch Socks.

Would you like to share how our socks performed for you after extended use?
Justin Wong –
Have you considered adding a heel-grip feature to prevent the socks from slipping down during long dives?
Imran Hanafiah –
Thank you for taking the time to share your feedback, Justin. We appreciate your suggestion to add a heel-grip feature to our Mares Flex 20 Ultrastretch Socks. This is a great point, and we will definitely pass it on to our product development team. In the meantime, some divers have found success with using a thin layer of sealant or tape on the heel of the sock to prevent slipping. Would you like to share more about your diving experiences with our socks?

These socks are extremely comfortable, I love how soft they are, but they don’t feel like they are providing the right amount of support for my feet
Joash Tan –
How big are these socks? I’m worried they might be too small for my feet as I wear a size 10.
Imran Hanafiah –
Thank you for reaching out to us, Joash Tan! Our Mares Flex 20 Ultrastretch Socks – 2mm come in a standard size, but we can ensure they’ll fit your feet comfortably. Our socks are designed to be a bit longer to accommodate different foot lengths, and the 2mm thickness provides a snug fit without being too tight. If you’re still unsure, feel free to contact us directly so we can help you determine the best size for your needs.

I’ve been wearing Mares Flex 20 Ultrastretch Socks – 2mm for about a month now, and I can confidently say they are one of the most comfortable socks I’ve ever worn. They stay in place well and don’t cause blisters or hotspots after long periods of wear.
Erica Low –
Does this product provide good moisture-wicking properties? I don’t want to get my feet all sweaty while working out.
Imran Hanafiah –
Hello Erica, thank you for your question. The Mares Flex 20 Ultrastretch Socks are designed for comfort and flexibility. They feature a moisture-wicking fabric that draws sweat away from your skin, keeping your feet dry and cool during your workouts. This fabric is also quick-drying, so your feet will be dry and comfortable even after your exercise is finished. I hope that helps!
Sharon Wong –
I initially thought these socks were a bit pricey, but they’re honestly worth every cent. They’re that good!
Lee Zhi En –
What’s the difference between these socks and other stretchy socks on the market? Is there something unique to this product?
Junhao Lo –
Thank you for your question, Lee Zhi En. The Mares Flex 20 Ultrastretch Socks – 2mm are made from a unique 2mm-thick neoprene that provides flexibility without sacrificing warmth. This specific thickness allows for a snug fit around the foot, preventing water from entering while providing a comfortable, smooth surface for swimming. Additionally, the technology used in the construction of these socks helps minimize friction and provides a smooth glide. What sets these socks apart from others is the balance between flexibility, warmth, and compression.
