I'm really loving this knit Oxford pair of shoes.

Things I love about them:
1) Super lightweight.
2) Ample airflow for nice cool feet.
3) Decent insole, especially for the price.
4) Looks really good, again, punching well above the price.

What may not go well in time:
1) They're super lightweight, will the fabric hold up? It seems pretty good. Also, the sole is basic hard foam with a coating, I assume it's going to wear down and not look the best. For the price though hard for me to complain.
2) The heel area is a bit on the floppy side (due to the knit construction, not much to do about it) which means it slips for me a little even though they fit true to size for me (9.5). I installed a foam heel cushion which has improved the stability. Not sure how well it will stay affixed to the fabric but it seems fine now.

If you fly a lot and want something light that packs away well I strongly suggest trying these out. I just did a 20+ hour flight day (8hr flight, 6hr layover, 7hr flight) and my feet loved me the entire time. That's rare for me.
