After reading so many great reviews on the Adizero SL2, I decided to try them out. It took a few runs to break in the foam, but the Lightstrike Pro foam is responsive and provides some nice pop. Some reviews recommended going up a half size, but a larger size wasn’t available (I wear a US size 13). While the length and width were great, the upper initially felt a little snug. However, they became more comfortable after wearing them for a few minutes before the run. The heel isn’t as unstable for me as some reviews have mentioned, especially compared to other shoes I’ve worn (e.g. Endorphin Speed). I’ve run up to 5K on these shoes and I would be comfortable running a 10k in them. I haven’t had any rubbing, hot spots, or blisters, but I have had challenges with lockdown on the right shoe. Perhaps a runner’s loop will correct this. I am rotating these shoes with the Supernova Rise 2 (which I love), but they provide a different running experience. I only have 20 miles on the SL2s, but they have been a really good shoe so far.

Great daily trainer, use it for all of my easy miles. Good for pickups too. Little narrow and a more stiff feeling foam but I like the versatility in foams in my running shoes.
