Hi, want to buy some Cortech Injectors off the net for $40. Problem is that i'm smack bang in between M and L sizing according to their size chart. For other gloves I find that i'm in the L range but they measure around the palm, whereas Cortech sizes only measure across the palm. Thus, not accounting for palm thickness. Should I get the Ms and hope they stretch out, or the Ls and try to use some product to shrink it?
