Tree Runner Go Sneaker (Men)

The color is 👌. The deep red can be a nice addition to different casual outfits that stands out, and walking in them is comfy overall. My only issue is the slight slippage in the heel. I wear 10's in two other Allbirds shoes with no issue and the rest of the shoe fits comfortably overall, but even when tied tight I can feel my heel slip (i. e. move up and down) slightly while walking. Could be the inner lining or shape of my foot, but I think the lower cut ankle may contribute. Heel pads don't seem to stick well or help much and thick socks only do so much. I can still walk in them fine and forget about any slip after a little while, though I'm curious if any slip will wear down the heel over time even in socks. I may be an outlier but the slip is the only issue. Consider sizing down half a size for a more snug fit. Really nice shoe overall.
