These are top quality. Made well. I do recommend.  But.  for me, I wear an 8 or 8 1/2.  Most recently (my last 4 pairs of shoes) have been size 8.  I ordered a size small 6.5 to 8 and med 8.5 to 10.  The small size 6.5 to 8 does not fit my size 8 shoes.  I mean it does fit.  But is loose. The shoes still retains a slight curve / bend in the toe area. Which you would expect shoes trees to prevent.  Also, because the shoes tree is relaxed at the max size 8, the split toes does not expand and fill the insides of your shoes.  I placed the med 8.5 to 10 in my size 8 shoes.  Because the spring tension was under pressure the toe bend went away, the shoes was straight. The spring tension forces the split toe out to fill the inside of the shoes so the cedar will actually absorb any moisture.
