These are soft leather boots with a back zip, very good quality leather as you would expect from Celeris. I bought them on here and they just turned out to be a bit too tight in the toe and wide in the calf for me. I would normally take a UK 7.5/8 and I would say my calf is about 15". These have signs of wear but have obviously been really well looked after, one zip pull is missing and has been replaced with yellow tape but that could easily be changed. The zips themselves work fine. I'm only hoping to get back most of what I paid for them, so they are a real bargain.
