I asked my husband to try on these trendy TIOSEBON men's sneakers. He found them very light, breathable and suitable for light walking. However, he noted that while the shoes are comfortable, they lack arch support and give the impression that he is wearing flat-soled pumps. In terms of sizing, we ordered size 12 and received shoes marked '46'. Husband said the shoes felt a little roomy but still fit. In fact, he was pleased with the extra space since he was able to fit a pair of curved, cushioning insoles into his shoes. Now the shoes feel great. Finally, although these shoes are good for everyday walking, they are not suitable for real sporting activities.
