To me foot wear is one of the most important pieces of safety equipment you can take on a river. How many of you have been on a river with someone who thinks it ok to bear hoof it and then when you need them to set safety or run along the bank to a pin but they couldn't move fast enough to get the job done because of bare feet. Now what if this person had to hike out? This other wise competent boater has now become a burden/safety hazard to your group.
Sorry about the rambling Ive just had one to many bad experiences(and Ive only had that one,and will no longer paddle a run with someone who is bare hoofing it)
As for shoes, I would recommend for Play boating and river running, the Teva Onium, And for creeking Either the Teva Avator(the full on creek boot) Or The Teva Gamma Pro.
Hope this Helps
id rather beg for forgiveness than to ask promission
