Kumite footwork 足捌き

Footwork in free fighting

What it is

In plain words

The patterns of movement that make distance controllable: sliding forward and back, stepping, switching the lead, entering at an angle, moving laterally, and leaving. Everything a fighter can do is bounded by where the feet can put the body, and how fast.

How it is taught.

The trigger that starts it, the distance and timing it needs, the decision it represents, and what it costs when it is wrong.

Mechanics
Forward and back by sliding — suri-ashi — without lifting or crossing the feet. Distance closed quickly with tsugi-ashi, the rear foot coming up before the front steps. Lead changed with a switch, both feet moving together. Angle entry by stepping the front foot off the line and turning the hips, arriving beside the opponent rather than in front. Lateral movement by sliding, never crossing. Exit by pushing off the front foot, at an angle wherever possible.
Distance
Footwork is how distance is manufactured. There is no other mechanism.
Timing
Movement is most useful on the opponent’s preparation — while they are gathering, they cannot adjust.
The decision
Straight back is the movement that changes nothing except the gap, and against an opponent who moves well it merely postpones the exchange while giving up the area.
The risk
Crossed feet cannot change direction. A fighter caught with crossed feet has no answer available at all.
Application
Continuously, throughout every exchange and between them.
4 faults

Common errors, and how to fix them.

Fault
The head rises and falls with each movement.

Why it happens. Pushing off with a straightening leg.

The fix. Move under an imagined low ceiling; a partner watching from the side sees it immediately.

Fault
The feet cross while moving sideways.

Why it happens. Walking rather than sliding.

The fix. Lateral sliding drills where crossing ends the round.

Fault
The guard swings with the footwork.

Why it happens. Using the arms for balance.

The fix. Move a full round with the hands deliberately still.

Fault
Retreating to the edge of the area without noticing.

Why it happens. Attention entirely on the opponent.

The fix. Practise inside a marked area from the start, not only before competitions.

Practice

Drills

  • Sliding up and down the floor in kamae, hands still, head level.
  • Angle-entry drill: partner attacks straight, defender steps off the line and finishes beside them.
  • Marked-square movement with direction changes called out.
  • A full round with no straight-backward movement permitted.

5 terms

The Japanese, explained.

Ashi-sabaki 足捌き
Footwork. The management of the feet: sliding, stepping, switching and turning without losing balance, height or guard.
Suri-ashi 摺り足
Sliding foot. Moving by sliding the feet along the floor without lifting or crossing them. The default footwork of free fighting.
Tsugi-ashi 継ぎ足
Following foot. Bringing the rear foot up to the front foot and then stepping forward with the front. Covers distance quickly without crossing the feet.
Ayumi-ashi 歩み足
Walking step. Stepping through so one foot passes the other, as in ordinary walking. Covers ground but changes the lead, which is a decision, not a side effect.
Maai 間合い
Engagement distance. The distance between two people, understood as a relationship rather than a measurement: the same gap is close for a tall fighter and long for a short one, and it changes the instant either moves. Controlling it is the largest single skill in free fighting.
