Hello, it is the third step described in outside spin , man part.
I wondered what it will be .
3/8 right turn from facing agaisnt LOD to DC ( RF fwd HT on 2 ) to facing DC, left foot lands side (to right foot) facing DC , then moves back and turns more 1/4 , facing DW?
(That meant partial body transfered to left foot before it heel down ?)
OR the back is left hip back beneath the body with lower heel?
As a lady, I only knew facing -DC, right turn to facing wall on my right foot ( HT ) then changed body weight on left BT continued my right turn responded to man's body facing -LOD then -DC , finally RF forward inside man's feet. ( 1/2, 3/8, 1/8 ) . head weight left -c - R respondingly. up right no sway. But if sway allowed or better ? In underturned outside spin, man's left foot is side and slightly back , it is easy to understand. But can I interprete it included two movements continuously : side, then back with right turn throughout it ?

Yichin. Outside Spin Alex Moore page 135. Usually danced after a Reverse Corte page 125 ). A complete turn between 1 and 3 for both man and lady.
The man's steps are simular to a Spin Turn but he leads his partner outside him on step one. Good Luck.

The last step of the underturned outside spin is very similar to the spin turn, but to get the full turn some turn is made during the last step.

The lady steps forward but then turns 1/8 so that the finished step appears to have been taken in CBMP.

The man steps to the side, then turns 1/4 so that the finished step appears to have been taken backwards. There foot does not move back, but if stopped at that point it would look like it had. As the lowering is at the end of 3 the turn is completed as or before the heel is lowered.

Wonderful for prompt response and great explanation.
According to book, I understood full turn in outside spin ( lady 1/2 ,on right foot , 3/8 then 1/8 on her left foot responding to man's body. I like your explained the CBMP result here ; I asked local coach last night about the man's left foot side then " end with" LF back. I showed him tiny toe in pivot on LF , right turn 3/8, then driving force from HT of right foot ( still small step ( Man is inside as an axis from 0-1-2 ), he turns himself and lady to right remained 3/8 and 1/8 on his left foot . I blocked my brain here: how can do " end with " back step on same standing foot ? Or weight not fully be transfered ? You gave me very good answer, now I understood the appearance of "end with "left foot back " is due to standing left foot on its side position continuously turn further ( 1/4 here ). Cheers!
Yes, He said " end with" not and with . not 2 actions from LF, but gave hint of an appearance .
