It's a strap on crampon boot. The Kento Guide takes semi-auto crampons although I think that has been replaced by a "Kento Advanced" model which is very similar. It's enough boot for most UK and Ireland treks even in winter. The Kento Advanced Pro is the insulated semi auto B2 model for trusting through snow and ice and the Taiss Light is the low weight B2 model. It's just a bit heavier than a trainer but performs like an ice climbing boot. They're all great boots & it all depends what you want them for & how much budget you have.
My wife has this boot and I'm pleasantly surprised by the durability. She came from all leather boots and had never thought "let's not out my foot there as it will rip up my boots" and yet hers look like new with some regular cleaning and spraying. The material (schoeller?) holds up really well. She had to size up though. Mammut sizing seems a little small.
