The space, or lack of it, in a Spyder footwell has been discussed a few times here. I generally wear Puma Speedcats, but they’re pretty pricey. When this China-spam popped up a last week I thought WTH, $25? I’ll give them a try.
They just arrived and for $25, I have to say they’re pretty nice. They come in tan and grey, and there’s a low-rise (ankle height) as well.
Like Speedcats, they’re pretty narrow, but I ordered my regular Puma size (46) and they’ll be fine with a little breaking in.
