Camp Blisters Are Preventable: What Kids' Socks Have to Do With It

Key facts

On June 2, 2026, the American Camp Association (ACA) convened a Capitol Hill briefing on child safety as more than 26 million children prepare to attend U.S. camps this summer. Pediatric sports medicine specialists and podiatric clinicians identify friction blisters as one of the most common and preventable foot injuries in young campers, caused by the combination of repetitive movement, heat, and moisture-softened skin. Sock construction, specifically seamless or flat-seam toes and reinforced heel zones, is the most controllable factor parents can address before drop-off.

• More than 26 million children attend U.S. camps each summer, according to the ACA.
• Friction blisters form when shear forces separate the skin's upper and lower layers, a process accelerated by sweat-softened skin and prolonged activity in new footwear.
• The heels and toes are the most common blister sites in young athletes, corresponding to the highest-friction zones inside a shoe during running and lateral movement.

What it means for parents

A blister that develops on the first full day of sports camp can sideline a child for the rest of the session. Unlike sprains or overuse injuries, friction blisters are almost entirely preventable with the right preparation. The most important variables are shoe fit, break-in time, and the layer of fabric between the foot and the shoe.

Clinicians at Nationwide Children's Hospital advise parents to treat any red, tender "hot spot" as an emergency early warning and cover it with moleskin or a padded bandage immediately, before a full blister forms. Children, unlike adults, often do not report foot pain until they are limping, so checking feet at the end of each activity day is a practical habit for camp counselors and parents on visiting days. Packing two to three extra pairs of socks for each day of camp, rather than one, gives a child the option to change into dry socks after a wet or heavily sweaty session.

Background and context

The ACA's June 2 Capitol Hill briefing focused primarily on emergency preparedness and climate risk at camps, but the organization's own data underscores the scale of the summer camp population in the U.S. - more than 20,000 year-round and summer camps serve 26 million campers annually. In that population, foot injuries are among the most common physical complaints during the first week of an overnight or sports camp, when children are wearing new shoes and covering significantly more daily ground than they do during the school year.

St. Louis Children's Hospital physical therapist Gabrielle Griffin, PT, DPT, noted in May 2026 guidance on summer sports injuries that persistent pain, limping, and swelling are warning signs that should stop activity immediately. Those signals apply to blisters as much as to soft-tissue injuries: a blister that breaks and goes untreated in a camp environment carries a real infection risk. Griffin also highlighted that children's bodies are still developing, meaning repetitive friction and pressure at the same points, day after day, can cause compounding skin damage rather than the gradual toughening seen in adult athletes.

Takeaway

Before packing for sports camp, check that your child's athletic shoes fit correctly with socks on, not off, and that the socks themselves have no raised seam across the toe box. A flat or seamless toe seam, a reinforced heel zone, and a breathable cotton blend address the three main friction-blister risk factors - toe pressure, heel shear, and sweat-softened skin - without adding anything to the packing list except a few extra pairs.
