The first time I tried on a pair of these Sidis, I knew I had to get them. When I choose my boots, I look for comfort, then protection and then durability. These boots hit top marks in all those categories. The leather that velcros around your leg, creates a snug fit and does a great job of keeping out the debris, while the outer plastic provides plenty of protection. The buckles are easy to adjust and effortless to lock in, but be sure to keep the top buckles snug because the inside might hook on the plastic of some bikes when loose. I ride on my arches a lot and wear through soles frequently on every brand of boot I have tried. The Sidis hold up as well as any, but a huge seller for me is being able to change the soles myself. The process is easy once you get the hang of it- as mentioned in the test, some of the fasteners do get worn, but instead of notching them to use a screwdriver, I found it best to loosen the ones you can and then just pull the whole sole off. The worn ones will easily suck through the sole, then just use some pliers to remove them. A single ten pack of new fasteners should cover the amount of worn out ones for the pair. I tried the enduro soles and the extra tread had really good grip, but made the boot a little too tall. I recommend sticking with the standard sole. The replaceable high wear pieces are also a great feature, but remember to check the screws regularly because they have a tendency to loosen up over time. From comfort to performance, these Sidis are at the top of my list- yes, they are pricey, but the quality is well worth the investment.
