adidas adizero Boston 10

I've owned three different pairs of Boston 12's.

The same exact story happened with the three of them:

For the first 70/90 kms (50 miles) they felt very hard, but after that, they became one of the best running shoes I've used in the last 20 years.

Yes, they are harder than your average shoe, but perfect for any kind of workout, tempos, long runs, fartleks and even recovery runs.

The sole is super sturdy and the Continental material truly is anti-slip even i n the slipperest conditions .

the upper is very good looking and also lasts a looong time.

In my experience, Most shoes last for 500/550 kilometers, but in each of my 3 pairs of Boston 12's, I've ran more than 700 kms and they are still going strong.

very happy with them.

The first few runs I was slightly concerned about the shoes being too stiff but they actually turn out to be perfect once broken in.   The biggest perk is that they start feeling amazing the older they get.   instead of worrying about my Boston’s getting too soft after a couple hundred miles I get to enjoy them without worrying.

At first I didn't like the shoe and they were uncomfortable compared to the other Adidas I've owned. After about 2 weeks of running in them though did they start to feel like comfortable and springy. 

Perfect for faster efforts. A little bulkier than the previous Boston’s but fits tight and narrow like a flat and feels great for faster intervals or tempo efforts. I use it for anything from 8 min pace easy runs to 5 flat tempos. Works great on road or gravel.

First off, these things are on the heavy side, and on the first 50-100 miles feel pretty stiff. However, as they break in, they are great daily trainer/long run shoe. I have not had any issues with injuries wearing these shoes, and perform well on even quicker long runs @ around 6:00 min/mi. Normally I only get around 400 miles on my shoes, but these are about to hit 500 miles, and the rubber still looks good, and have not dealt with any soreness that shows up sometimes with worn out shoes. Wouldn't be surprised if I get another 100-200 miles on these. Boston 11 is pretty similar, and usually able to find a good deal on Bostons.
