Vintage STUART Stuart Wiseman leather sling back wedges NWOT Size 8-1/2 +/-

STUART Stuart Wiseman vintage leather sling back shoes in a lemon yellow with a black leather angular heel. The bow on the instep is a mesh material trimmed in the yellow leather. The heel measures appx 3-1/2" and these have never been worn. No box. Posted for a friend, she notes that one of the leather wrapped straps' seam has opened (pictured). Also said she believes these are marked Size 10 but they are not and measuring the sole, it is appx 9" from toe to heel. The interior measures about 10" from the point of the toe to the heel which is more in line with a size 8-1/2 give or take. She said she would put them on from time to time on a carpeted floor but never wore them anythere after paying what she paid - and they've increased a lot since then!
