These are socks from a Thai brand, and what impresses me personally is that I’ve been a long-time customer of Runnercart. I’ve been supporting them since they first opened their store four years ago. My passion for running socks led to the perfect combination of global-standard quality at an affordable price. It’s no wonder that Personal Best Performance Socks are currently their best-selling socks.
Now, let’s talk about the newly released Personal Best Double Slash running socks and how they’ve improved from the first version.
1. New Compression Design

After putting them on, the compression feels not much different from the previous version. It’s comfortable without feeling too tight, though it does feel slightly more comfortable than the older model.
The Achilles tendon support, which other brands don’t offer, feels like it’s in a better position than in the previous version. But as for whether I can feel it while running, I can’t. However, the brand has surveyed athletes with injuries, and the results show that it really does provide support.

Overall, in terms of compression, I personally feel that it’s more comfortable than the previous version.
2. Impact Support

The thicker the socks are on the soles, the better they support impact. The pad on the sole of the new version feels slightly thinner than the previous one, so I feel that the older version provided slightly better impact support on the soles.
3. Ventilation Band

Just above the ankle, there’s a ribbed ventilation band, which is one of the highlights of this Double Slash model. I can clearly feel how comfortable it is when running, with air flowing all the way to the skin and more heat escaping through the ventilation ribs. It’s a sock-knitting technology that really appeals to runners.
There are a few minor drawbacks, though. The socks tend to slide down more easily than the previous version while running, but they don’t bunch up at all, as they only slide down a little.
4. Fit

They still fit as well as they used to. The socks are already compression-fit and have an elastic band that wraps around the midfoot and arch, so they don’t move while running.
5. Brand Logo Detail

This version features an embroidered brand logo. It’s a round patch attached to the top of the sock, positioned right above the heel collar of the shoe. It looks cool in photos—I love this idea!!
As for whether it chafes, it doesn’t, because it’s not pressed against the shoe’s edge.
6. Finishing

When I turned the socks inside out to inspect them, I saw that the inside of the band had no seams and the stitching looked very neat. You can really see the quality of the manufacturing. They’re worth the price, and most importantly, because the finishing is so good and there are no seams, anyone who is sensitive to sock seams can rest easy.
