I currently own last year's Olympus pair and love them. However,  the tread is not aggressive enough,  so I thought I'd try these. Big mistake! I knew there would be some reduction in cushioning with these,  but it was far less than I expected. Very uncomfortable. Plus after just one trail run, several of the lugs on the bottom of the shoe are torn off or damaged. Very disappointed with these. One word about size: this brand tends to run small. I go up a full size.
