adidas adizero Boston 11

In 2023 I ran my first Comrades Ultra Marathon in an ASICS GlideRide 2, My marathon PB was 04:10:36, which I used for as my Comrades qualifying time. I then finished the race on 10:58:37. In September 2023, after retiring the shoe, I started using the Boston 11. After training in January 2024, I ran a qualifier in a PB best of 03:52:57. When I ran the 2024 race, I finished it in a time of 09:59:48. Best decision I made. Now looking to upgrade two a Boston 12.

Heavy and very stiff. I dont understand the concept of adding the carbon rods to this trainer who is very heavy and already very stiff. The whole shoe construction is bad and it already ruined 2 of my running socks by the heal

...but maybe that's because I ran in a different shoe for so long. These feel really stiff to me, but either I'm breaking them in or I'm getting used to them. I sound negative, but that might not be fair. I tried on the Boston 12s and then bought the 11s online and they just feel very different. They seem like a solid trainer so far.

I have run 10 runs in them and they are still not broken in, I tried running a 20km long run and my feet felt dead after. They are good for short runs under 5km at a slow pace 

Boston 11's great shoe, but be patient, it takes a good 5-7 runs, before they get broke in.

Not a bad shoe, firm, but well cushioned. Decent flex for having the rods, but the upper is terrible. What happened here adidas? Air mesh came out like 10 years ago on shoes. I'm confused by these upper materials. Hot spots everywhere and my feet are pretty normal, no weird bunions or bumps. 

A decent trainer I am still breaking them in; they feel good for the amount of miles I log.

Nice for uptempo easy days. Somewhere between a trainer and a flat. 

Bought for $40 on sale on adidas.com because its a last gen shoe and color was ugly. I used for short speed work going about 23 sec per 200 and they felt good. Very stable shoe, not as fast as racing flats or spikes but they are much easier on the legs with the padding and stability. Better to sprint in than any other big trainer I've used. Also did lots of easy miles in them and they were great for that too- on par with other trainers like pegs that I have used.
