OMG! I've been looking for a pair of sandals with those pressure points for years. About 8 years ago, I bought a couple of pairs of sandals from QVC last clicks, they had plain leather "Birkenstock" style straps, and a spongy footbed with these "impact" points dotted about the insole,and they were an absolute joy to wear. I wore both pairs until they literally fell apart, and haven't been able to replace them.......
HOWEVER....I wouldn't be seen dead in those hideous monstrosities! Trust IW to find the ugliest, gaudiest pair of sandals in Christendom...seriously, I wouldn't even wear them for a bet!!!!!
