Climbing Shoe Review - La Sportiva Genius & No-Edge Technology

Since buying my Genius a fair few people have asked me what I thought about them and more specifically the no-Edge technology. I have now owned my La Sportiva Genius for 5 months so I feel I can finally pass judgement on them and the No-Edge technology. When you look at one you can’t help but look at the other - So here you have somewhat of a mixed review. First a bit of background on the new tech.

No-Edge Technology

At first, like many, I was somewhat sceptical of the No-Edge technology La Sportiva were pushing on some of their more high-end boots. Boots have had good edges for years; it’s one of the things many people look at when they are buying a new shoe. Deep down everyone knows you need an edge to stand on those tiny little “Credit Card” edges. And we have all had to throw away a pair of shoes that are just too worn down - a big sign of which is their lack of edges.

According to La Sportiva however, none of this is necessarily true. A “No-Edge” shoe is produced using a brand-new process, meaning that La Sportiva can make the following claims:
  • No-Edge brings rock and foot into closer contact.
  • No-Edge enhances the sensitivity and the adaptability of the shoe.
  • No-Edge allows for a more even pressure distribution across the shoe.

There are a few things to consider here, that once your normal shoes are worn down enough to be edge-less the rest of the shoe is used and abused to the point where they don’t function as they should. And while an edge is great for standing on a tiny crimp the extra rubber you have to put on a shoe to produce an edge will obviously reduce sensitivity - More rubber on the shoe, means more rubber to have to feel through.

Another question we could ask, is why did we want Edges in the first place? I mean I can see the logic of them being great on crimps but are they useful on any other hold type, that is to say “Does a shoe’s edge offer any advantage on a hold type other than a thin lip?” Are we maximising gains on one specific hold while causing losses on all the others? I can’t really find a satisfactory answer to this anywhere, but at least this is an interesting point for another time.

Anyway enough general waffling and onto the shoe itself.

Comfort
As a rather aggressive shoe the genius is not a comfy out of the box boot. However they broke in within a handful of sessions and really sat nicely on my feet. Wearing them untied at first decreased the discomfort but probably also increased the amount of time to break them in. The lace system obviously allows for the shoe to mould very closely to one's foot, while the Classic La Sportiva P3 system maintains the downturn and hence the feel of the shoe. There is a ridge of padding under the curve of the toes which took a bit of getting used to, but is actually a really nice feature and does increase the comfort overall. One great feature is the full lacing system, allowing a really adaptable fit for a range of different foot sizes and shapes.

Sensitivity
I originally bought these as a stiff shoe, on both the shelf and the test pair the rubber felt stiff while still being flexible. However after breaking in the Genius has become much softer, still not as soft as say the Python’s but still noticeably softer than they first were. The sensitivity is brilliant; you really can feel a lot of what is going on underneath you. I was worried about whether my footwork would become more shoddy - just stabbing a foot on and letting the No-Edge technology do its job - however this isn’t so much the case. You are not so much just stabbing a toe on and just going, but there is no time needed to make sure the edge is on just right. You can feel the rock beneath you, know you can weight it and be straight off again.

In The Gym
I’m not sure this is the shoe for you if you solely use them in the gym. They are an expensive pair of boots and honestly I’m not sure feet are ever so bad in the gym that an edge will be what’s holding you back. That’s not to say I don’t use them when indoors, but if this is your only stomping ground I wouldn’t be rushing out to buy a pair -Though I will say that I have started using them during training board sessions, and they are very useful at getting your feet used to that specific sort of precision footwork.

On the rock
This is where the genius really shines. The amount of information you receive from your toes is simply phenomenal. I have had these out and about all over Yorkshire and Peak grit. They are good at everything from standing on pebbles and quarried ledges, to smearing on non-existent holds. Recently they were my go to shoe for a week in Fontainebleau, where they performed exceptionally well on the glassy and non-glassy sandstone of the area alike, even performing well on even the most delicate of Font slabs. The one thing I haven’t mentioned is how great they are at heel-hooks. The stiff yet sticky heel holds really well, is easy to weight and even easier to trust.

Overall

The Genius is a great bouldering shoe, fulfilling all the needs of a performance rock boot. They are built fantastically well and given the good state they are still in after 5 months of use that quality seems to last. For those of you who take a selection of shoes to the crag, this is definitely one you need to consider, and I am sure you would quite quickly be pulling this one on first. It can take a while to get used to but it is definitely worth it.  The “No-Edge” technology can be a bit of a Marmite style divider, but for my money it works - and don’t let that be what puts you off trying a brilliant shoe.
