Great style, great performance. Dries fast. Perfect grip in the water and cushioning on land. Fits as expected; considering it's (mostly) a sock and not a shoe. 1/2 size makes it perfect!
Pros
Prevents rocks from damaging your feet when boarding and disembarking our kayaks.
Cons
Not very durable. The Colorado River tore them apart in about a dozen hours. Take J-41.
