Irish dance basic step: skip or promenade step

Having brought the movie of a "Siege of Ennis" I thought it would be interesting to explain how to dance it.
But first you need to know the steps that are used in this dance: skip (or promenade step), side step (or 7 step), rising step. Well, I'll have to test my analytical-descriptive skills...

One of the main features of Irish dance is that arms are generally still along the body. Steps are performed on point, bringing one foot always in front of the other one (or behind, depending on the direction!), in a straight line.

Let's start with the skip.
Position: right foot in front of the left foot, right heel touches the left foot keeping the tips slightly open).
1) having the right leg close to the left knee, bend the right leg, bringing the foot upwards, with the peak tension (= hop, on the weak time of the music or take off): This movement is a kind of intersection, then you point the right foot forward and you load the weight on it (= one, on the beat or time)
2) move the weight on left foot, which remains behind (= two)
3) bring back the weight on the right foot (= three): in this way the left leg is free to move and bend backward (= hop) preparing the next step.

At this point you start over again (1) with the left foot. However, since the left leg is behind you do not do the "cut", but just bend backwards your leg, bringing then the foot forward: hop, one, two, three, hop, one, two, three ... up to exhaustion.
If you want to move back, the movement is similar, only the 1) is made bringing the right foot behind the left.
