Title says it all.

Myself and my friend both have the Katanas. She's on her second pair, and this is my first pair. After the first week the rubber was starting to de-laminate from the upper toe but didnt progress to a point that warranted reipair or return. 3 months later, both our shoes have the rubber delaminating slightly on the inside edges - not good.

The fit is great, the performance is good for a velcro and the rubber is top notch as always with LaSportiva.
I might try something different next.
