White Mountain Toleen Women's Platform Sandals for Summer Outfits

I ordered these for a 90s themed event. The insoles are very padded and have great arch support. The straps are easily adjusted for a comfy fit.Unfortunately I misread the nubuck color as also being a nubuck upper. Instead the upper is very plastic-y and is unlined. It makes the top of my foot sweat and blister from that. I used a blister prevention stick before wearing them, but still got blisters. I have worn them for several hours over three nonconsecutive days and fear they may never be comfortable enough to not leave blisters.
