I've actually just got the Bareback Quebec boots, I have quite a high instep and I couldn't get the ankle ones on so I've kept the longer version. I need these for dog walks too, I don't find wellies very comfortable.
I absolutely hate making a decision on new footwear though - I ordered £600 of the Bareback Boots to try on, waited till the last day to send them back and still feel anxious that I'm not going to get on with the Quebec boot! I put them on to wear out round the field with our dog on Saturday, then chickened out and took them off!
I've got a pair of the Bareback Chicago waterproof boot from last year and I wear them all winter to work, it is a good brand. I also kept a pair of the navy suede ankle boots in this order for wearing with winter dresses etc, replacing a very old M&S pair that are done!
