Foot Sweep

Family

足払い(Ashi-barai)

Traditional

Translation: foot sweep

Overview

The Foot Sweep family covers techniques where the attacker uses their foot to sweep the opponent's foot or ankle out from under them while simultaneously directing the upper body in the opposite direction. [1] Foot sweeps exploit timing and the opponent's weight transfer — the optimal moment for a sweep is when the opponent's weight is shifting onto the target foot, making it the sole point of balance. [1],[2] Sweeping that loaded foot away creates an instantaneous base collapse. [2] Foot sweeps are predominantly drawn from judo's ashi-waza classification and include techniques like de ashi barai, ko soto gari, okuri ashi barai, and sasae tsurikomi ashi. [2],[3] These techniques are among the most technically refined and timing-dependent takedowns in any martial art. [3]

History & Origin

Foot sweeps are fundamental to judo, where ashi-waza was classified as one of the five main throwing categories by Jigoro Kano in the Kodokan system. [1] Japanese martial arts refined foot sweep timing to an extraordinary degree, with techniques like de ashi barai considered the most technically demanding throws in judo. [2],[3]

Effectiveness

Foot sweeps use precise timing to sweep the opponent's foot during weight transfer, requiring minimal energy but excellent timing. [1],[2] They are among the most efficient takedown techniques in combat sports. [1]

Lineage

Foot sweeps are a defining category of judo's ashi-waza, codified by Jigoro Kano in the Kodokan syllabus. [1] They also appear in Muay Thai as teep-based sweeps and in wrestling as foot blocks. [2]

Competition Record

Foot sweeps are high-frequency scoring techniques in judo competition at all levels, from local tournaments to the Olympic Games. [1]

Biomechanical Mechanism

Primary ActionPenetrating step and level change to attack the opponent's legs — disrupting their base of support
Joints InvolvedAttacker's knees and hips (level change), opponent's knee or ankle (controlled point)
Force VectorForward and downward — closing distance and driving through the opponent's lower body
Takedown MechanicRemoving one or both legs from the opponent's base forces them to fall or be driven to the mat

Position & Entry

From clinch rangeEstablish upper body control (collar tie, underhook, or body lock), obstruct the support leg with a trip or sweep, and drive the opponent to the mat
From grip fightingUse push-pull action to shift the opponent's weight, then attack the loaded leg with the trip

Training Notes

The sweep must arrive at the exact moment the opponent's foot touches the mat with weight transferring onto it
Use both hands (tsurite and hikite in judo) to control the opponent's direction and timing
The sweeping foot stays light — it redirects rather than kicks
Pull the opponent in the direction of the sweep with your hands to amplify the effect
Practice the hand action and footwork separately, then combine them
Foot sweeps are highest-percentage when the opponent is moving — catch them mid-step

Common Mistakes

!Sweeping when the opponent's foot is in the air (no weight) or fully planted (too stable) — timing must be at the moment of weight transfer
!Kicking the foot instead of sweeping it — a sweep is a smooth redirection
!Relying on the leg sweep without using the hands to direct the opponent's balance
!Sweeping with the wrong part of the foot — use the sole or the instep, not the toes
!Standing too far away, reaching for the foot with a straight leg
!Trying to sweep a foot that the opponent is deliberately keeping light

Sub-techniques

De Ashi Barai

SubFamily

De Ashi Barai (advancing foot sweep) is a foot sweep subfamily where the attacker sweeps the opponent's advancing foot at the moment it contacts the mat, using a lateral sweeping motion to knock the foot out from under the transferring weight. [1] The technique requires exquisite timing — the sweep must be executed at the precise instant the opponent's foot touches down and begins accepting weight. [1,2] The attacker uses the sole of the foot to contact the outside of the opponent's ankle or lower shin and sweeps it in the direction of the opponent's toes. [2] De ashi barai is considered one of the purest expressions of judo's principle of maximum efficiency with minimum effort. [2,3]

Ko Soto Gari

SubFamily

Ko Soto Gari (minor outer reap) is a foot sweep subfamily where the attacker reaps the opponent's heel or ankle from the outside using the sole of the foot or the heel, while driving the opponent's upper body backward over the reaped leg. [1] The 'minor' designation distinguishes it from o soto gari (major outer reap) — ko soto gari uses a smaller, more precise reaping action targeting the ankle rather than a full leg sweep. [1,2] The upper body drives the opponent's weight backward onto the heel, and the reap removes that support point. [2] Ko soto gari is effective at close range and from various clinch positions. [2,3]

Okuri Ashi Barai

SubFamily

Okuri Ashi Barai (sliding foot sweep) is a foot sweep subfamily where the attacker sweeps both of the opponent's feet simultaneously or in rapid succession as they slide laterally, catching both feet together with one sweeping motion. [1] The technique exploits lateral movement — when the opponent is moving sideways, there is a moment where both feet are close together and the weight is transferring between them, making them vulnerable to being swept as a unit. [1,2] The attacker drives the opponent laterally with hand control, then times the sweep to catch both feet at the moment of transfer. [2] Okuri ashi barai produces spectacular, seemingly effortless throws when timed correctly. [2,3]

Sasae Tsurikomi Ashi

SubFamily

Sasae Tsurikomi Ashi (lifting-pulling propping ankle block) is a foot sweep subfamily where the attacker blocks the opponent's advancing foot with the sole of their own foot while using a lifting-pulling hand action to direct the opponent's body over the blocked foot. [1] Unlike sweeping techniques that remove the foot, sasae blocks the foot in place and rotates the opponent's upper body over this fixed point, creating a rotational fall. [1,2] The technique requires the attacker to time the block with the opponent's forward step and simultaneously create a strong circular pulling action with the hands. [2] Sasae tsurikomi ashi is one of judo's most elegant techniques, demonstrating the principle of using the opponent's force against them. [2,3]

Frequently Asked Questions

After I sweep someone with an inside foot sweep, what should I do next?

Coach Brian recommends turning to hunt for their back as you come down from the sweep. You may end up in half guard, and from there you can transition to mount if both their legs are down.

Why is the inside foot sweep useful in jiu-jitsu specifically?

In jiu-jitsu, people typically go to guard after being taken down, so Coach Brian emphasizes getting the knee leg in during the sweep to control that outcome and set up your position more effectively.
