Mogema XR1 Racing roller blades. Excellent shape hardly used. Low rise. Too tight around ankles for me, but the boots are "Thermoformable for 12 min at 70°C". I think they are size 10.

The boot and the frame can be separated by two special bolts from underneath. Sometimes they are sold separately.

Frame is a "Cros2" "Dual Box". Three 100mm and one 84mm. (3x100x84).

The amazon site uses the phrase "for fast recreation". This might imply that the 84mm wheel gives a bit more stability-maneuverability than four or five 100mm wheels in a row. The latter, presumably, would be for racing, i.e. a steady clip on a very smooth surface. Otherwise I haven't found a discussion or explanation.

Front: Hyper Race neutron 85A 100mm (beige)
next: Calvano Outdoor Race 84a 84mm (black)
(the axle on this 84mm is a bit lower so that all the wheels are on the ground)
next: Hyper Race neutron 85A 100mm (beige)
Back: Hyper Race neutron 85A 100mm (beige)

They are very light weight.
