Lots of summer shoes are suede, but they tend to be unlined suede. I assume those boots are leather lined? Alden makes unlined suede chukkas and loafers. Clarks are unlined. There are all kinds of suede summer shoes - I just don't think those boots are in that category. They still look good to me, especially in that lighter color, but something lower ankled and unlined makes more sense with that outfit.
