Lining gamma 1

hey guys, really intrigued with gammas and would like to get the perfect size considering the price. For reference, i have 361 5.0 quick pros in 8.5US which fits perfectly - about half inch space in the toe area. Another shoe i have is wow10 lows in 8.5US as well but the length is a tad shorter compared to my 361. The fit is a little too constricting. I would love to have a similar fit to my 361. Can someone share their insights?
