Different socks

I did a pair of socks for a lady she has badly swollen legs & feet so this pair i just did a size larger & used larger needles on the rib

She still had trouble still with the rib also she said a shorter leg so i came up the idea of doing the rib still on the larger needles but straight needles & not on the round once the rib done i changed to the smaller DPs needles the lady said these one fitted perfectly so as you see in the photo the open rib, i will be doing her another pair 
Both pairs are done in 4 ply yarn
