shoes will simply give support to keep up warm

When you yourself have some knowledge with stitching, that technique is handy. A flexible group may tighten the sneakers, creating them smaller and tougher to slide off. Only stretch the elastic band and sew it on the back of the shoes to pull the material together. When you release the band, it will draw in the material of the shoes, giving them a tighter fit. If the heat and water strategy fails or wearing thick socks is inappropriate for your shoes, think of shoe fillers to make them fit.
