Typical rubber boot support. Could not wear these for any length of time before my feet started to hurt due to the lack of support.<br />We had a lot of rain here in Texas a few months ago. I was wearing them to take the trash to the alley as the yard was like a marsh. After coming back in I noticed a high pitched whistling noise coming from the boots (both of them). It sounds like a pinhole air/water leak. No water in the boot itself, yet.<br />Overall not impressed. Expected better for the price. Would have returned them but I missed the cutoff date.
