I have a pair of hd boots that are lace up with side zip they are a very comfortable boot for riding and walking what i would call an all day boot
However there is no flap behind the zip and i have forward controls they point the toes out slightly and put the zip in the best area for catching any water thrown up by the front wheel abot 2 miles on a really wet road and feet are wet i dont like wet feet

I have also wondered why they don't make a MC boot with the zipper in the back of the boot, much like some womens boots I have observed. That seems to be the best place to avoind scratching chrome and keeping the zipper out of the line of water spray.
