Alpinestars - Bionic Pro Plasma Knee Protector

Anatomically profiled for all forms of off-road riding, the Bionic Pro PLASMA Knee Protector has been engineered to be lightweight, breathable, comfortable and protective, and features a removable Nucleon PLASMA knee protector embedded into a chassis that is abrasion resistant on the outer and highly breathable on the inner for maximum performance.

  • Constructed with a soft tactile inner padding for enhanced rider comfort.

  • Pre-shaped construction features soft touch perforated stretchable padding for enhanced comfort and superior airflow, with extra lower and side padding for extended coverage.

  • The anatomically sculpted upper calf and upper hem silicon strips keep the protector secured in position.

Kids?
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I didn’t realize these were kids socks, until after I got them, but the fit is amazing and they stay put, without coming off my heels. I wear an 8.5-9 in women’s shoes.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!
