Not only do the K2 Mach 90 men's inline skates offer fast, agile high performance on long cruises and fitness outings, they do it at a mid-range price point. Both buyer reviews and an expert review from InlineSkates.net owner Steve Kopitz are extremely positive, citing comfort, a supportive boot/cuff, high speed and high performance as reasons to buy this skate. However, like the K2 T:Nine Celena, this may be too much high-performance skate for a beginner, especially once you get going fast.
A video review from InlineSkates.net is our best source of authoritative information for the K2 Mach 90. The reviewer goes into detail about every one of the skates' features, although he doesn't compare the K2 to other skates. This skate also received a smattering of very positive user reviews on Amazon.com and Buzzillions. The scarceness of user (and expert) reviews is typical of the inline skates field.
This expert review from Steve Kopitz, skate buyer and owner of InlineSkates.net, describes the K2 Mach 90 as "a true high-performance skate." Of particular note, Kopitz points out the skate's "super-high performance wheels and bearings," which provide a fast, comfortable ride. Because the review is in video format, you get to see Kopitz pointing out specific features as he reviews them.
Review: Steve Kopitz, May 6, 2011
Amazon.com lists reviews for both the 2010 and 2011 models of the K2 Mach 90. The former receives five 5-star reviews, the latter receives two 5-star reviews. Reviewers repeatedly describe a smooth, comfortable ride on these skates, and the only complaint made is that occasionally the hook-and-loop strap snags the laces. A few reviews imply that, like the K2 Celena Women's model, the Mach 90 may be a little too high-performance for beginners.
