A good economic ankle brace for someone like me thats broke both ankles twice. Nothing fancy, just tight extra support. Does want to make you loosen your boots a little to accomodate the extra "bulge".
The EVS brace is a much higher quality brace than the 661 however the EVS has a plastic inserts to add stability to the sides. i find the inserts to be very uncomfortable in a boot. i tried trimming them but still too uncomfortable. I like the 661 better but still a great buy if you have weak ankles
