Lacing techniques for heel lock and swollen feet

The runner's loop, window lacing and wide-forefoot lacing. Simple lacing changes that stop heel slip, ease pressure points and handle foot swell.

How you lace your shoes changes how they fit. A few simple techniques solve common problems like heel slip, pressure on top of the foot and tight toes.

Heel lock (runner’s loop)

Problem: heel slips.

How: Use the extra eyelet at the top of the shoe. Thread each lace into the top eyelet on the same side to make a small loop. Cross the laces and thread each through the opposite loop. Pull tight.

Useful for sled pushes, lunges and burpees where the heel lifts.

Window lacing

Problem: pressure on the top of the foot.

How: At the pressure point, skip the cross — run the laces straight up the same side for one eyelet, then continue crossing.

Wide forefoot

Problem: tight across the toes.

How: Skip the lowest eyelets, or lace them loosely, leaving more room at the front.

Swollen feet mid-race

Lace firmly at the heel and a little looser at the forefoot. You can loosen further mid-race. See shoe fit for long races.

Double knots

Laces coming undone in a race costs time. Double knot them, or use lace locks.
