Why Daiso Korea's running gear sold out
On April 30, 2026, Daiso Korea launched about 60 running clothing and accessory items in collaboration with the sports brand HEAD. It was the first time the chain had partnered with a brand on running gear at this scale, and with most items priced at KRW 5,000 (about US$3.50) or less, many sold out within days. The running vest, which holds a water bottle and a phone, drew more than 10,000 restock-alert sign-ups on Daiso Mall, according to Korean press reports.
The running boom in Korea shows in the numbers too. Industry reports said Daiso's sportswear sales in January–April 2026 were up about 200% on the year before, and sports accessories such as sweatbands, armbands, and towels were up about 40%. These products are sold by Daiso Korea, which is separate from Daiso in Japan and the US, so the HEAD line is a Korea-only find. If you are visiting Seoul and want to try running along the Han River paths, it is an inexpensive way to get kitted out.
What it costs and what to check
Prices below are as reported in the Korean press. A second release and restocks have followed, so items and stock vary by store.
| Item | Price | What to check |
|---|---|---|
| Running vest | KRW 5,000 (about US$3.50) | Does it bounce with a bottle and phone inside? Does it rub under the arms or on the shoulders? |
| Lightweight windbreaker / anorak | KRW 5,000 | For cool mornings and evenings. You warm up fast, so look for thin, breathable fabric. |
| T-shirts, half-zip tops, shorts, 7/8 leggings | KRW 5,000 | Quick-drying technical fabric, and seams that will not chafe |
| Sports socks | KRW 1,000–2,000 | A snug fit with no wrinkles at the heel or toes |
| Caps and gloves | KRW 3,000–5,000 | Sun protection in summer, warmth in winter |
A T-shirt (KRW 5,000), shorts (KRW 5,000), socks (KRW 2,000), and a cap (KRW 3,000) come to KRW 15,000. Add a windbreaker or vest and you are at about KRW 20,000, roughly US$14. That is the "full outfit for KRW 20,000" Korean media talked about, and a low-risk way to find out whether running is for you.
What to look for in budget running clothes
- Fabric: cotton soaks up sweat, gets heavy, and chills you. Check the label for polyester or another quick-drying fabric.
- Chafing: on longer runs, the armpits, inner thighs, and chest can rub raw. Try items on and check where the seams sit.
- Sizing: Korean sizes often run smaller than US or European sizes, so try before you buy.
- Visibility: if you run after dark, look for reflective strips. If there are none, choose bright colors.
Why shoes are worth buying separately
The reported Daiso × HEAD line is clothing and accessories. Shoes have the biggest effect on how running feels, so spend what you saved on clothes there. That does not mean expensive shoes prevent injuries: the evidence that cushioning or "anti-pronation" designs reduce injuries is inconclusive, and researchers have suggested that simply choosing the shoe that feels most comfortable to you is a sensible approach (Nigg et al., 2015).
- Try both shoes on and jog a few steps in the store. Feet swell later in the day, so afternoon fittings are more accurate.
- Leave about a thumbnail's width beyond your longest toe, and make sure the forefoot is not squeezed.
- If your everyday sneakers are comfortable, they are fine for the first few weeks of walk-run sessions.
What running does for health after 50
A meta-analysis of 14 studies from six cohorts with over 232,000 people (Pedisic et al., 2020) found that runners had a 27% lower risk of death from any cause, 30% lower cardiovascular mortality, and 23% lower cancer mortality than non-runners. Even small amounts, such as once a week or under 50 minutes a week, were linked to lower risk, and running more did not clearly add further benefit. These are observational studies, so healthier people may simply be more likely to run, but the message that a little running counts is consistent.
The World Health Organization and the US Physical Activity Guidelines both recommend 150–300 minutes of moderate activity or 75–150 minutes of vigorous activity a week for adults, including those over 65. Running usually counts as vigorous, so you get there in less time.
How to start
Trying to run 30 minutes non-stop on day one is the fastest way to quit. The UK NHS's free Couch to 5K program builds up over nine weeks, three runs a week, by alternating running and walking.
- Walk briskly for 5 minutes to warm up.
- Alternate 1 minute of running with 1 minute 30 seconds of walking for 20 minutes (week 1 of the NHS plan).
- Run slowly enough to talk in short sentences.
- Rest a day between runs. Three times a week is plenty.
- As it gets easier, lengthen the running intervals and shorten the walks.
You may have heard the "10% rule" (do not increase weekly distance by more than 10%). In a trial of 532 novice runners (Buist et al., 2008), a 13-week program built on the 10% rule had the same injury rate as a standard 8-week program: 20.8% vs. 20.3%. Pain is a better guide than percentages. If one spot still hurts the day after a run, rest or switch to walking.
Check with your doctor before you start if
- You have heart disease, diabetes, or kidney disease, or have had symptoms such as chest pain or dizziness. The American College of Sports Medicine (ACSM) advises medical clearance before starting exercise in these cases.
- You take blood pressure or diabetes medication, which can cause low blood pressure or low blood sugar during exercise.
- You already have knee or ankle pain. Building fitness with walking or water exercise first is another option.
Stop running right away if you have
- Chest tightness, pressure, or pain, or pain spreading to the arm or jaw
- Unusual breathlessness, dizziness, cold sweats, or an irregular heartbeat
- Sharp pain in the heel or shin
If chest pain or breathlessness does not ease with rest, call emergency services (119 in Korea, 911 in the US, 999 in the UK).
Seasonal tips
- Summer: Korean summers are hot and humid. Run early in the morning or after sunset and drink water before and after. Stop in the shade if you get a headache, nausea, or dizziness.
- Spring and autumn: temperatures swing a lot between morning and midday. Start in a windbreaker, then tie it around your waist or tuck it into a vest once you warm up.
- Winter: protect your hands and head with gloves and a hat, and avoid icy paths. Warm up indoors on cold days.
If your calves and thighs feel tight after running, a Daiso foam roller can help you loosen up. See Daiso Foam Rollers and Massage Balls: How to Choose and Use Them.
