The bottom line The best-documented boot on the shelf, and the one whose documentation disagrees with itself.
Two flex figures in one listing
The title: Fischer RC4 60 JR GW … Flex 60.
The detail line: Flex: 50.
Flex is the number this boot is sold by. A 50 and a 60 are a real difference to a child of the weight that takes an MP 24 — one bends when they lean, the other does not.
This page does not decide between them. It prints both and says the listing disagrees with itself.
The sole length belongs to another boot
The detail line reads Sohlenlänge: 257mm (bei MP21.5) — sole length 257 mm at Mondopoint 21.5. The boot being sold is MP 24/24.5.
Sole length is the measurement a binding is set to. Taking 257 mm to a shop for this pair would set the binding for a smaller boot.
What it gets right
GripWalk, named as the sole and named again as the binding compatibility. Two listings in eight do this, and it is the specification that decides whether the boot fits the skis already in the garage.
The rest of the detail line
Niveau: für sportliche Youngsters. Farbe: schwarz. Größe: MP24/24.5. Level, colour, size — published, along with an easy entry and exit system the maker returns to in three of its five bullets.
Availability
One check, one figure — 148 € — at the German Amazon shop.
Outside the euro, the American Amazon shop sells it in its own currency, and the range above is kept clear of that.
On the shelf, off the market: the British, French, Italian and Spanish Amazon shops carry the reference with no seller attached to it.

The declared figures, and where they run out
Strengths
Names its sole standard and its binding compatibility, which six of the eight listings here do not
Publishes a detail line at all — flex, sole length, sole, compatibility, level, colour and size in one place
A GripWalk sole is the one that walks on snow without skating on it, which on a child’s boot is the difference between the car park and a fall
Compromises
The flex is 60 in the title and 50 in the detail line, and the listing never resolves which the boot is
The sole length is given for MP 21.5 while the boot sold is MP 24/24.5, so the figure does not belong to this pair

Questions asked about this one
Is it a flex 50 or a flex 60?
The listing says both. The title reads RC4 60 JR and the detail line reads "Flex: 50". This page reports the contradiction rather than choosing, because the difference is exactly the kind a buyer pays for.
Why does the sole length say 257 mm?
Because the detail line gives it "bei MP21.5" — at Mondopoint 21.5. The boot on sale is MP 24/24.5, so its sole is longer than 257 mm. Sole length is what a binding is adjusted to, so this figure has to come from the boot itself, not from the listing.
What is a GripWalk sole?
A rockered, rubberised sole that walks better than a flat alpine one. Not every binding accepts it, which is why the listing states the compatibility alongside the sole. See the standards page on this site for what the convention covers.
Who this one is for
A child skiing regularly, on skis whose bindings are set for GripWalk
