The Lux is our feminine classic flip flop with an EVA top sole, diamond textured footbed and thin matte PU straps for breathability. Dress up or down with this extremely versatile style! Our products fit a little small. If you are normally a size 5 then we would suggest you buy the size 5/6 if you are in-between our sizes, say a 6.5 we suggest you go up rather than down, therefore a size 7 would be our suggestion.
