Robbie And Nathan have to be shaking their heads at this repeated effort to classify shoes as for either Sport or Boulder. The Boostic is for standing on minuscule but distinct edges with precision, think off vert welded tuff with xenoliths and awkward pockets or shallow vesicles especially, whereas the Booster is for standing on small divots and irregular surfaces with precision, think windswept sandstone and granite along ribs and huecos. The Boostics come out with me alongside my Chimeras for about everything.

It's interesting to see how mat chose worse but lower clipping positions with the soft shoe, probably because they gave him less confidence in his feet

I'm a big dude, but actually really like soft shoes for sport climbing. The Boosters are actually my "Stiff shoe" for sport climbing right now, next to my Solutions.

My opinion of “sport climbing shoes/bouldering shoes” is that you should piick the shoe that works for the boulder/route. There is so much variation in climbing that’s it seems closed minded to say “this is a sport climbing shoe” etc.

It's all about terrain, not sport vs bouldering. Steeper usually means softer and more downturn, more vert usually means stiffer and moderate camber. The RRG in Kentucky is a sport mecca, but you want a soft shoe because of how steep it is. Squamish has some edge-y vert-ish boulders that suit stiff shoes. Best to have a quiver.

I think you made the actual point when you said you're heavier. It's all about weight. The Booster, as many others shoes, are unisex model so it's really obsolete to declare whether they're soft or stiff. They're probably too soft for a climber above 70 kg while they could be perfectly fine for a climber below 60 kg.

Interesting test. What size is Theresa - a 'soft' 37 is a lot stiffer than the same shoe in 42,43

nah matt, second go up looked much harder for you!

Been wearing the Boostics for a month now - I'm 220lbs, they're sized very tight at a 44, and I bought them to replace my Muria VS's. I have to say, they are fantastic - the Muria's are definitely stiffer, but the fancy tension systems in the Boostics actually make it EASIER to stand on tiny holds, even with the shoes feeling a bit thinner and way more sensitive. You can actually feel what you're standing on! Also, if you have high arches and a thin heel with a flat Achilles, these shoes will fit much better than most. They dont have that "bulb" style heel cup that most LaSportivas seem to have. Honestly couldn't recommend a shoe more - for heavier guys there arent many options and these are fantastic.

it is all question of weight.

I like soft shoes no matter if I'm sport climbing or bouldering and I feel insecure with most edging type shoes. Seems to me a much better distinction: Is a shoe better at smearing type of footwork (think no edge) or edging type footwork.

Hi! This model performs like the Miura VS?

Bouldering vs sport... The footholds on the climb matter more than the number of moves.

Such an great comparison.

Do both heels fith the same? The new Booster heel was to baggy for me :(

How about a comparison between the boostic and the katana lace from la sportiva? Seems like direct competitors instead of doing the Boulder vs Sport shoe comparison

does anyone know the name of the climb?

Love from India ❤️❤️🔥

Is there a reason why scarpa focus so much on narrow shoes? Their only wide performance shoes seem to be the VS/VSR

Shoes are not meant for a specific type of climbing. They are designed for the type of footholds that you will be climbing on.
