Why is the heel of the sole sticking out so far? For proper stride? Other than collecting, what are these intended for? Running?
I definitely would love to try a pair, but right now I can't afford ****. Having chronic foot, leg, back problems, I really want to see what this boost hype is all about. How is the insole that comes with them? Good arch support? Is the boost mushy?
I run in all my ultra boosts. Have about ~1300 miles across three pairs. They fall apart pretty easily (two of my three soles have cracks in them) and the laces fray easily. If you're not careful when running in them, they really do put a little bit of extra stress on heels (reason being is that the boost doesn't exclusively act as cushion but also adds springy-ness, so your heel does more work when landing your foot), but I'm the kind of runner more likely to have knee problems, so that's okay with me. Also, they're heavy and can run a little hot (the primeknit stuff on top or whatever helps, but it's still not as nice as the mesh you can get on some ultralight runners).
But now that I finished that paragraph of ****ting on them, they are the greatest running shoes I ever had. They're so damn comfortable and I never have sole or ankle problems. I don't feel confident on a race day if I am not wearing my boosts, and honestly feel like together we make a team. The springy-ness I complained about before makes running downhill effortless (I mean literally, even in long races), and makes flat running pure relaxation. The insoles are great, even when wet (that's something I never thought I'd say), but are prone to wrinkling a little and shifting around easily if you make it a routine to clean them out. If I didn't have to compete with ****ty collectors, I wouldn't even look at other shoes. As it is, I'm considering buying the Adizero Adios 3 and the Adizero Boston 6 to see if their boost can be just as nice.
I previously ran in New Balances Minimus Zeros for lightness (and zero drop when I was in on that fad), Saucony Ride 7s for cushioning, and Under Armour Speedforms for comfortable fit. None of those experiences compare, and now I expect a completely different quality of 'cushioning' from every shoe I ever wear. That said, I am also the only person I know irl with this opinion. All my running buddies find them to be 'too much' and prefer something both lighter and with less cushioning, so your mileage may vary (pun intended).
