Footwear sizes can vary across brands and style we cannot make an exact perfect recommendation on comparing them against other brands and boots. However, when we tested them with our team we found that most ran "true to size".
For reference, if you wear a size 8 in most brands including Vans, Nikes, Merrell Boots, Red Wings, etc; a size 8 in our MACV-1s and Jedburghs will likely be your best fit.
If possible, we do suggest you order two different sizes to compare if you are unsure and send the pair that does not fit.
Returns that are unworn and in their original condition can be returned within 30 days of the delivery date for a full refund (minus shipping). So we recommend testing them out inside on carpet or a place where they will not be damaged or show any wear or tear.
