If you are mechanically inclined installation should be easy for you. My husband gets the top rows since he?s the tallest, I get the middle, and our young son gets the bottom. I used it for the first time at an outside event that was very windy. If you dont like, (leave the tags on em) and send em back. as long as you can comfortably wear them. My issue was that the strap rubbed my Achilles? heel on my right foot, which would have been avoidable if I had been able to adjust the tightness of the ankle strap. I love that its wireless and TEAMs compatible so that I can quickly get on and off a TEAMs meeting. Con altre crocs trovate bene I was initially concerned with it being too big but after a number of rides I think its just the right size. Overall I gotta say this is a good value at its price!
