De-ashi-barai - the advanced or advancing foot sweep. De-ashi-barai is best performed at the precise moment that the ukes foot comes forward just before the foot is firmly planted on the ground, as their weight is being redistributed towards that foot.
The sole of the foot needs to be used by the tori, or it is possible to damage the side of their foot. The timing on this technique is the most difficult aspect - but it is still possible to throw the opponent if they have advanced the foot asn it is planted (but much more difficult).
Can be difficult to distinguish between this and Ko-soto-gari - simply the direction of the uke's fall (to the side with De-ashi-barai, to the back with Ko-soto-gari) shows which technique was used.
