Why the surfaces all look the same
Line up any two synthetic ice surfaces and they are hard to tell apart. Most use the same kind of connection system and share the same white appearance. With nothing visible to separate them, and every manufacturer claiming the best glide, a buyer has little to compare but price and understandably settles for the cheaper option. That is a reasonable response to a genuine lack of criteria, not a mistake. What follows is how to compare properly: a scientific look, beyond the obvious, at what actually makes a surface good.
What "best" actually means
A synthetic surface is judged on four things: surface friction, indentation, abrasion, and whether it is flat and even. The first three are the real engineering and they trade off against each other; an even surface is the baseline you should expect from anyone. The three that decide how a surface skates are explained below, each with the one independent measurement that exists for it. For the full definitions and the physics behind them, see What is synthetic ice?.
The three measured properties, and how the surfaces compare
There is a single independent, published dataset in this category. The Fraunhofer Institute for Mechanics of Materials IWM, Europe's largest organization for applied research, measured the five leading synthetic ice surfaces on the same purpose-built rig, under identical conditions. Glice came out best on all three. Here is what each property is, why it matters, and how the surfaces compared. The full method is on the Fraunhofer measurement page.
Surface friction: how hard the blade is to push
Friction is how much resistance the blade meets, and it is the property a skater feels most directly: low friction is what lets a blade glide instead of drag. It is also the easiest to be misled by, because a friction figure only means something measured under known conditions and against a reference. In the Fraunhofer test, Glice recorded 52% less friction than the next-best surface, at low sliding speed on clean samples.
Indentation: how far the blade sinks
Indentation is how far the blade sinks into the surface under load. It matters because practically all regular synthetic ice is too soft: the blade sinks in and the skater ploughs the material aside instead of gliding over it, like an icebreaker ship forcing through pack ice, which is tiring and wears the blade down faster. Blade edges last only while skates stay on the ice or rubber matting; hard flooring or asphalt ruins them fast. It is as decisive for glide as friction, and almost nobody asks about it. Glice recorded 45% less indentation than the next-best surface.
Abrasion: how much the surface sheds
Abrasion is how much material the surface sheds as it is skated on. Too much means constant cleaning, a surface that degrades faster, and shavings that cling to skaters. It is the quietest of the three, but it shows up in maintenance and in how long a surface lasts. Glice recorded 6% less abrasion than the next-best surface.
How to read any comparison
A single friction number proves nothing on its own. Friction is a system, so a figure only means something when you know the conditions it was measured under and what it was measured against. The Fraunhofer study has both, which is exactly what most competitor claims lack. For a named, verifiable head-to-head against one competitor, see Glice vs PolyGlide. When a supplier gives you a "better glide" claim with no conditions and no comparison, treat it as marketing, not measurement.
Beyond the surface: what decides a rink's success
The best surface is necessary, but it is not the whole story, and any serious "best synthetic ice" decision has to account for that. A rink's success also depends on things a laboratory never measures: the look and quality of the dasher boards, which decide whether a venue feels premium or cheap; the installation guidance, staff training and ongoing support a supplier provides, which decide whether the rink is actually run well; and marketing, location and maintenance, which decide whether people come and keep coming back. These are judgement, not lab results, and they are covered on the Why synthetic ice rinks fail and Running a successful rink project pages. When you compare surfaces, compare the whole package, not just the friction figure.
How to choose for your situation
The best surface for a back garden is not the best surface for a thousand-skater theme park. Once you know the three measured properties and have seen the data, the practical next steps are to interrogate the supplier properly, which is what the How to choose synthetic ice checklist is for, and to read the economics for your specific setting on the relevant industry page.
In short
The best synthetic ice is the one that measures best on friction, indentation and abrasion under stated conditions, and then supports a rink that actually works. On the only independent comparison of the five leading surfaces, Fraunhofer measured Glice best on all three, with 52% less friction, 45% less indentation and 6% less abrasion than the next-best. Anything claimed as "best" without conditions or a comparison is a claim, not a measurement, and the surface is necessary, not sufficient.
