Run (Ladder)

A run—called a "ladder" in British English—is a vertical line of unraveled stitches in hosiery. When a single thread breaks or snags, the knit structure unravels along that vertical column, creating a visible line that can extend the entire length of the stocking or tight.

How Runs Happen

Hosiery is made with a warp-knit structure where threads loop together in columns. When one loop breaks:

  • The loop above it loses its anchor
  • It unravels and releases the next loop
  • This chain reaction continues up and down
  • Result: a visible vertical line of missing stitches

Common Causes

Cause Prevention
Fingernails Wear gloves when putting on, keep nails smooth
Rough hands Moisturize, use cotton gloves
Jewelry Remove rings/bracelets, watch for rough clasps
Velcro Avoid contact with shoes, straps, bags with velcro
Rough surfaces Be careful sitting on wood, wicker, rough chairs
Toenails Keep trimmed and smooth, wear foot pads
Wrong size Size up—overstretched hosiery snags easier

Emergency Fixes

When a run starts, you can sometimes stop it from spreading:

  • Clear nail polish: Dab at both ends of the run to seal broken threads
  • Hairspray: Spritz the area—the stiffening can slow spreading
  • Fabric glue: Small dot at run endpoints
  • Run-stop product: Specialty hosiery repair product

These are temporary measures. Once a run starts, the structural damage is done—you're just slowing further unraveling.

Run-Resistant Hosiery

Some hosiery is designed to resist running:

  • Different knit structure: Warp knit modified so a single break doesn't cascade
  • Reinforced threads: Stronger fibers at stress points
  • Thicker denier: More material = harder to snag

Run-resistant doesn't mean run-proof—it just means a snag is more likely to stay as a small hole rather than becoming a full ladder.

Run Prevention Habits

  • Moisturize legs: Smooth skin snags less
  • Remove jewelry: Before putting on hosiery
  • Use gloves: Cotton gloves for handling sheer hosiery
  • Bunch before wearing: Gather fabric before putting foot in, then smooth up
  • Size correctly: Hosiery under tension is more vulnerable
  • Store properly: Flat or rolled, away from jewelry and zippers
  • Hand wash: Machine washing damages fibers

When Runs Are Fine

Runs have been embraced as a style element in some contexts:

  • Punk/grunge fashion: Intentionally ripped tights
  • Pre-ripped styles: Hosiery sold with deliberate ladder patterns
  • Distressed look: Worn, casual aesthetic

Pro Tip

Keep a spare pair of pantyhose at work and in your bag. Runs happen at the worst times. A backup pair saves the day.
