Inov-8 is way too narrow for me. Toe box on the Terroc 330 and Roclite 295 wasn't bad, but the midfoot and heel was dangerously narrow. Which is a shame, since seemed very nice.
Not used the La Sportiva X Country or Cross Leather, but the Wildcats have worked out very well for me. Very stable, wide enough for my 2E feet, none of the annoying heel slippage I encounter with so many shoes.
