Ko-soto-gari into De-ashi-harai.

Combination (Renraku-waza).

Techniques
----------
1. Ko-soto-gari (小外刈), the minor outer reap.
2. De-ashi-harai (出足払), the advancing foot sweep.

About
-----
The small outer reap chases your partner into a step, and the stepping foot is swept as it advances.

Step by step (standard right-handed form)
-----------------------------------------
1. Take your right grips and reap the outside of their right heel with the sole of your left foot.
2. Feel them save the foot by stepping away with it rather than falling, so both of you are moving.
3. Put your left foot down and travel with them, keeping the sleeve tight so their upper body stays with yours.
4. As their left foot advances, and just before it takes their weight, sweep it sideways with the sole of your right foot.
5. Pull their sleeve down and across as the foot leaves the mat so their shoulders follow their feet.
6. They land on their side; keep the sleeve so their head stays supported.

Receiving it
------------
The first reap does not take you down, it makes you move, and that is the point of it. Once you are stepping, the foot that is travelling is unweighted for a moment and that is the one they sweep. Expect the second attack to arrive on the beat of your step rather than after it. Chin tucked, slap with your free arm as your side meets the mat, and keep the held arm long so your head stays clear.

VI judo notes
-------------
Ashi-waza against a moving partner is timing through the grips, and the reap is what makes the timing yours: you decide when they step. Keep the sleeve tight while you both travel so their body is where your hands say it is. Movement is the part worth drilling with a coach calling the space, especially near the edge.
