I mostly run in Nike Free5.0's - having 4 pairs of them size 9 - 10.5 ( took a long time to get the size right!!) I like them a lot - however they are a bit "squeezy" in the toe box. I can and do run all distances ( up to 15K so far) in them but use the smallest size 9 for 5K only. They are very light and flexible.
BUT - while I was in the US earlier this year, I was lucky enough to grab a pair of outdated ( 2013) Brooks Pure Drift shoes for the miserly cost of $35 USD ( about $45AUD- these shoes run up to $200 AUD where I live!) Like the NIKES they are very light and flexible - but much wider. They look almost strange to wear - looking down at them , I get the feeling that I have a pair of reef shoes of swimming flippers on -- but boy are they comfortable. As I said - like wearing a pair of slippers ( where is my pipe??) . I have read elsewhere that running shoes should feel like they are slippers -- these are very light though with very little sole padding and only 4mm heel to toe drop. When standing in them , I feel like my heel is actually lower than my forefoot - although that can't possiby be so. I think these may become my 5K PB attempt shoes from now on!!!
