Are Boost shoes worth the extra weight (Takumi Sen 3)

I weighed a type a and a takumi sen 3 just last night, in the same size, on digital scales, and the takumi was actually 10 grams lighter (for a single shoe). There's no good reason to believe the manufacturer's weight claims.

They are worth the extra weight, but they aren't worth the extra price in my opinion.

The adios boost is simply fantastic. The price tag however is (still) a kick in the nuts.

I'm debating getting the Takumi Sen 3 for 5 and 10Ks, but they're 6.1 ounces.

Alternatovely I could forego the boost tech and go lighter (e.g. mid 4 ounces).

So the question: is the running economy gained from higher energy return worth 1.5-2 additional ounces of shoe?

I currently wear Saucony Type A6's for flats, but I'd like to go either down in weight or move to boost. Torn!

Dude. I was about to make this thread. I wear a few pairs of Boosts for casual but the pricetag is steep for running.

Been curious about these for 10k/HM.

Sounds like you need the Sub2

Yeah I wouldn't pay $160 for flats, but they're 85 bux on running warehouse at the moment.

Not to hijack the thread completely, but would anyone consider wearing the Takumi Sen for a marathon? I'm trying to decide between the Takumi Sen and the adios 3. I've worn the Saucony Type A5 for all races up to the half. I think it's the best flat I've ever used. I tried on the Type A, but it's a completely different shoe. It didn't work for me at all. Thanks in advance for any help!

Anyone ever tried the Feather?

For me the TS3 are the shoes to buy, especially at the discount price. I changed to them for races last year and PRed in every distance from 5k to marathon. Not saying they were the only reason but they definitely played a big part. Very, very good shoes.

You can do the math.

Original boost saved 1% vs. EVA

There is a 0.8% penalty per 100 grams at racing speeds.

1 oz = 28 grams

however, you also need to take into account the cost of having less cushioning. that's harder to do, but this is a good place to start.

If I did another marathon I would run in TS3s. I did my first marathon, Chicago, in Flyknit Racers but they have zero durability for a $160 pair. The AA3s are a great shoe but the upper stretches and has a wide forefoot. I got blisters halfway through Boston because of this. If you look at the birds eye view on RW you can grasp how wide the toebox is.

Right now I do speedwork or intervals in the TS3s and they feel amazing. I've loaded up on them for the next few years - just bought my 4th pair in the last six months even though the first one still has a lot of life left. 6pm.com has them for $67.99. Get them before they are gone!

Thanks for the tip. I just order a pink pair. I hope I like them.

Hence adizero Sub2

yes, if you can only choose Adidas.

but there will be better options soon.

Cool, thanks! I ordered a pair of the Adios on the recommendation of a friend, but I went up a half size. I'll wait to see how they fit. Now I'm worried they'll be too long and wide. I'll probably just go ahead and order a pair of the Takumi Sen, too. I really like the specs of them online. I'm not sure if they'd be a marathon shoe for me (6'2", 150 lbs, time of 2:35-2:40), but they look like they'd be great for 10k to 13.1. Thanks again!

Hope you guys like them but you should be able to return without hassle.

I went half a size down on the TS3s because I like spikes and racing flats to be snug.

i've worn the takumi sens in a half marathon (last year's san diego 1/2--a national championship meet for masters--ran 1:11:06), and was very impressed by them. i typically blister up in longer races, but did not in the takumi sens, but i also wore toe socks for the first time, so hard to know what may have been responsible for me not blistering up.

i also wear the takumi sens for track work, but personally prefer the asics piranhas for 5ks.

hope this helps,

cush

I did the opposite. I went up a half size for my order because the reviews on the runningwarehouse site recommended that. I'd rather have a bit large than a bit small, even for racing shoes, because of the bunions that make my forefoot wider. I'll see when it comes in.

Christian, hop on the TS3 deal from 6pm.com. $67.99! When are you racing next?

i'm racing carlsbad in a little over a week, then the oc 1/2 (also a national championships) in may.

have you ordered from 6pm.com before? i've read some negative reviews, so i'm reluctant--sometimes when the price is too good to be true, it's too good to be true...
