A medium-volume all-mountain alpine boot on Atomic's 100mm last, the most common foot shape. The 100 flex is the easy end of the Prime line: supportive without fighting you all day. The change on this version is the closure — a BOA H+i1 dial on the lower shell wraps the forefoot evenly instead of clamping at two buckle points.
This is a BOA-lower plus two-aluminium-cuff-buckle boot — not full BOA, not a three-buckle boot. The GripWalk soles (ISO 23223) need GripWalk, MNC, or MN bindings, and there's no walk mode. It's a resort boot.
The easiest-flexing boot in a respected all-mountain line, and the BOA lower is worth trying if buckles have bothered your forefoot. Get a shell fit and a mold before you commit — on boots, the fit decides everything.
