The &#34;not having to tie&#34; feature is nice for putting on, but that also means that one cannot adjust how the shoes feel across the top of the feet. To attain the most comfortable fit required only three pumps. The fit is true to size.  These happened to be 1/2 size larger than our normal purchase, but the fit was fine because of the pump adjustment. The shoes are not bulky or too heavy, in spite of the &#34;technology&#34;.
