Overshoes with clips and straps?

If you really want your feet to stay dry I've got some gore tex chainsaw boots you can buy off me

they weigh a little over 1.2kg each, but your feet will definitely be dry when you take them off

real men ride in cofra strong 3's

i've ridden my surly miles to work while subcontracting over the last couple of weeks.
chainsaw boots ftw. toasty warm, dry and able to resist a chainspeed of 28m/s. ftw.
hopefully will be jol-compatible**™

**i use plastic bags inside my shoes normally. classy.
