Last month I ordered a pair of C&J Saviles. Â I wear a US 11D so I ordered the Saviles in a 10.5E. Â The 10.5E turned out to be too big, so I went down 1/2 size to a UK10E. Â There was still some slippage with the right shoe, but I figured it was due to the fact the shoe is a monkstrap. Â Today I received a pair of C&J Belgraves in a 10E, which slip worse than the Saviles. Â Could it be possible that I need to drop 1.5 sizes to a 9.5E?
