Hi Mic >>> I don't think it is. These sort of boots often have a little metal "tab" which fits under the foot by the frog to stop the boot moving around. See http://www.astund.is/index.php?id=24&activemenu=24?_cat=92&catalog_item=1334
Do you think it is metal - we had boots that had a piece that fit into the heel groove on the frog but they were rubber unless this is a new and 'improved' model. Robyn Icelandic Horse Farm Robyn Hood & Phil Pretty Vernon BC Canada www.icefarm.com
