OK what about equestrian clearence warehouse in sowerby bridge they have a website its mail order. From what i remember they are very reasonable. Just found the link for you www.equestrianclearance.comDerby House is way out of my price range unfortunately
Well what i would suggest then if you cant find any to fit is to buy the largest pair you can find then take them to a local saddler and have them put an extension in for you. That is what i had to do with treadstep chaps.Tried them aswell, cant find any big enough for me. Tried evry single website i can find!
