They feel so good. As all my other KEEN shoes are. In regards to shape, it is very similar to the GPW with a bit more weight. At first, I was concerned that these would slip off my feet easily, but I have found them to be better fitting and not needing adjustment like the elastic trimmed styles. Im so glad I bought it. Putting pillow cases over the sandbags could make the setup more presentable. We have gotten almost 2 years out of the dance store ones which are still in great condition being used several times a week, but they are now too small. Perfect for summer or winter. I will see what happens when I get them out again this summer. I shot them an email from their Youtube page and they work with me to try and remedy the problem.
