Perfect fit due to adjustable strap length none
provides just the right amount of support without losing moch of the joint's flexibility
Comfortable and nice fitting and very effective.
Very supportive for whole knee - front and back Gets uncomfortable and not very adjustable
I have tried a lot of different knee supports over the years. The best of them provide firm support unobtrusively so you can wear them for a long time without really noticing. The Aptonia does the first bit: it's tight (had to change size!) and the cross strapping provides support to front and rear of knee. However, it isn't adjustable and I found it felt tighter and more uncomfortable the longer I wore it. I think this could have been better designed, possibly with a rear velcro fastening strip to allow adjustment, rather than the all-or-nothing pull-on sock approach.
