The IQON ACT Interlink is a good inline skate boot-only for urban and aggressive use, on which three frame mounting standards can be used.
Keep in mind that it is a hardshell that comes without a liner. You have to buy a liner separately here: Sliding Tiger liners for inline skates.

What' is "Interlink"?
With "Interlink" the manufacturer means that on the inline skate boot three different standards of frames can be mounted: UFS frames, 165mm frames and Trinity frames. The necessary adapters are included in the box.

A removable soulplate is included too. A soulplate is necessary for aggressive inline skating, but if you are not interested in grinds, you can remove it and use the skate as an urban skate.

What's in the Box?
- the black Iqon ACT Interlink boot of course
- and as written hereabove: NOT a liner
- a grey ACT soulplate
- the Myfit Double infusion casted PU and EVA MYFIT shock absorber
- a Myfit size adjuster
- the ACT Trinity and 165mm adaptors
- a Kizer supreme buckle (that's mounted already on the hardshell)
- a tool for the axles
- a lot of screws to mount the various adapters.

Strengths and weaknesses
- The biggest strength of this inline skate boot-only is at the same time its weakness. It's quite impressive that three frame standards can be mounted on the inline skate boot, but it comes with a cost. When only one frame standard can be used on a boot, that boot can be optimized for that one mounting standard. When three standards are possible, some compromises have to be made in order that the three standards can be mounted. (The main drawback is that there is not really a forward lean with the 165mm and Trinity adapters.)
- You have to buy a separate liner, but at the same time, then you can choose every liner that you desire, also of other brands.
