On the left is the Admire Leather Wedge Boot by Acne and on the right is Neve Black Grained Nappa by Senso.
Well, you can see the similarity in style with both shoes. Both have the drape and buckle strap detail but the Neve doesn't have the exposed zipper tape opening and there's a slight heel to it. Hands down, the original Acne boot still looks best. If you do love this style, the Senso is definitely more affordable with its US$200 price tag compared to Acne's US$680.
