I have just completed a 10 day canoe trip on the Buffalo River in Arkansas wearing the Mion Flood Tide Shoe. The shoe was excellent, as was the river of course. In the past I have used sandals, but on a river like the Buffalo the rocks and pebbles constantly worked their way between my feet and the sandals. However, with the Mion Flood Tide Shoe, the mesh liner kept out the rocks, pebbles, and most of the sand. But especially praise-worthy was that they fit my feet!!
They have a roomy toe box, and are adjustable enough to also fit around my high instep. They were comfortable to wear all day long, drained well, and gripped those slippery Buffalo River rocks as well as any footwear I ever wore down there. But don’t expect too much in that regard. Nothing prevents slipping on those Buffalo River rocks.
So after 10 river days experience, I can’t recommend them highly enough for people with wide feet.
