I went from ions to selects.
I wasn't impressed with the ions. I got the selects a few weeks ago and ridin them once and pretty much have had them on around the house a few hours a day. From what I can tell from only riding once is they are a better choice then the Ions
The select is a lot more compfy and less room to move around I felt the ions where boxy any alowes my foot to move side to aide
And the selects lacing system really is a step
Above button IMO, it just seems you have more control over the ammount of tighness in the top and bottom.
I realy like how the liner in the select holds your foot as well. It has two Velcro
Tabs at the top that extend over that really makes it asnug fit. You don't have to over compensate by tightening areas of the boot more then other, the boot itself just fits my foot 100 times better then the ion
They seem about the same stiffness as the ion cause both are stiff boots. But tw selects have an insert that stiffens the boot up
