Solite kitesurfing/surf booties brand new small

Brand new!  Ordered a 6.5 woman’s (which I wear), but they seemed too small.  I tried them once, and were WAY too tight!  I couldn’t use them.  I think they should be a size 5 womens or child’s size, and can be heat molded to fit.  I have been injured the past two years, so they have been sitting in my basement.  Time for someone else to use them.  They are awesome, just didn’t fit, so I ordered a different size.  They retail for $80.  I can ship!  Image shows my 6.5 foot compared to these.
