Racing in brand new shoes is one of the most common race-day mistakes. Even a shoe that feels perfect in the shop can cause blisters or feel different on the sled after an hour.
Why break them in
- Find problems early: rubbing, pressure points, heel slip.
- Learn the grip: how the shoe feels on the sled.
- Soften the upper: some uppers need time to shape to your foot.
- Confidence: you know what to expect.
How many sessions
A few sessions is usually enough for most modern shoes. Include at least:
- One run of race distance or longer.
- One station session with sled, lunges and wall balls.
- One race simulation. See race simulations.
What to check
- Rubbing or hot spots.
- Heel slip.
- Grip on the sled.
- Stability on wall balls and lunges.
- Comfort after an hour.
Do not wear them out
Keep race shoes for race-specific sessions so they still have good grip and cushioning on race day. See when to replace training shoes.
Timing
Buy race shoes several weeks before the race. That leaves time to break them in, or change them if they do not work.
