Gear Fit for Growing Bodies
Harnesses that fit, shoes that do not hurt, and when to replace worn kit.

Harness fit
- Snug at the waist and sitting above the hip bones, so it cannot slip off
- Leg loops comfortable but not loose; buckles doubled back as the maker instructs
- Check the manufacturer’s weight range - some harnesses have a minimum weight
- For very young or slim children, a full-body harness is often the safer fit
Shoe fit
- Snug, not painful - kids should not be wincing or curling toes hard
- Children’s feet grow fast; size for now and re-check often
- Beginner flat shoes are better for young feet than aggressive performance shoes
When to replace
- Outgrown shoes (toes jammed, heel slipping) or worn-through rubber
- Harnesses with frayed webbing, faded stitching, or past the maker’s lifespan
- Any gear involved in a significant fall or shock load - when in doubt, retire it
Helmets
Helmets are standard outdoors and for some lead settings to protect against falling objects and head-first falls. Indoors, follow the gym’s policy. A helmet must fit level and snug to do its job.
A quick check before each climb
Buckles done up and doubled back, knot or belay device correct, shoes on properly, nothing tangled. Teaching kids this routine builds a lifelong safety habit.
