A thin-sock option for the range
KIPRUN Run900 Thin Mid-Calf socks add a conventional thin running-sock option alongside toe socks and other specialist designs. Decathlon Singapore lists the yellow version under reference 8939259 and describes a snug fit, elasticated support and material that absorbs and wicks perspiration.
Decathlon markets the yarn to limit rubbing-related irritation. That is the manufacturer's design positioning, not a promise that wearing the socks will prevent every blister.
Why compare thickness?
Sock thickness changes how your existing shoes fit. Consider this model if a thicker sock makes the shoe feel crowded or you prefer less material around the foot. Runners who like extra cushioning should compare it with a thicker option instead.
Try the socks in the exact shoes you intend to run in. Check toe room, heel fit and whether fabric bunches. A thin sock that feels good in one pair of shoes may feel different in another last or size.
Check the exact Run900 version
Run900 is a family containing thin, thick, invisible, strap and other constructions. The directory entry covers Thin Mid-Calf. Do not transfer features from a different Run900 sock based only on the number.
The researched UK white model page provides additional construction and care details, while the Singapore yellow listing has its own reference. Regional and generation differences should be checked on the delivered label. No universal composition or weight is asserted for every colourway.
Practical preparation
Decathlon's detailed model guidance recommends testing and washing new socks before using them in a race. Use an ordinary training run to assess the shoe-and-sock combination rather than changing it for the first time on race day.
Check the size range in both shoe-size systems if buying cross-border. Compare price per pair and package quantity; a single pair and multi-pair bundle are different buying units.
Buying in Asia
The Singapore listing was marked out of stock when researched, so confirm the selected size or store availability. The Singapore button is direct; the Indonesia button is an affiliate-linked Shopee search rather than a vetted seller.
