If you need a half-size simply add these insoles to reduce the size by one half size. For example: order a size 9 clog, add the half-sizer insole and the clog is now a size 8 1/2. Makes any pair of Sloggers shoes or Boots 1/2 size smaller. Perfect fit for in-between sizes or those who want to tighten the fit up a bit. Cut-To-Fit design. Adds extra cushion.
