Item arrived earlier than expected from Great Lakes Outpost (kudos to seller). Also nicely packaged. The fit and height adjustment of this shoe as it molds properly to your foot for a comfortable fit. I have used mountain bike shoes in the past and immediately noticed their ability to transfer power uphill and how light they are. Highly recommend, and not bad considering the Sidis can cost upwards of $600. I bought this on sale during the Sidi week promotion.
