Ariat made their name in English boots but the total catalogue is now overwhelmed with western boots and western casual wear.
Tredstep actually had a note of apology up on their main Irish home web site saying they’d solved recent supply problems and could guarantee delivery again. Like Ovation and Mountain Horse they are fully equestrian focussed, and English equestrian, which isn’t true about Ariat anymore. But interestingly they carry far fewer models than Ariat. One dress boot each.
