Axiom says of the Proxy:
"The Proxy shares the Envy mold’s core, lending the same low-profile feel and solid grip, along with a short wing width and wide flight plate diameter for superior glide. The Proxy sets itself apart from the Envy with a remarkably straight forward-fading finish. A bit of high-speed turn potential allows the Proxy’s lines to be manipulated over a broad range of power, and helps less powerful throwers achieve straight putter drives."
Simon Lizotte proves the utility of this disc as his go-to throwing putter and approach disc from all distances.
